The conjugate of the expression 4 - (x + 5) is formed by changing the minus sign to a plus sign, resulting in the expression 4 + x + 5, which corresponds to option D.

The conjugate of a binomial expression like 4 - (x + 5) is obtained by changing the sign between the two terms. Hence, the conjugate of this expression would change the subtracted term (-x - 5) to its additive inverse, which is (+x + 5). Therefore, the correct choice is 4 + x + 5, which is option D.

The area of the frame is found by subtracting the area of the photograph from the total area of the framed photograph. After simplification, the expression for the frame's area is 24a + 4a². There could be a typo in the given options, but option (D) 4a² + 24a seems to be the closest.

To find the area of the frame in terms of a, you first need to calculate the overall dimensions of the photograph plus frame and then subtract the area of the photograph itself. The width and height of the entire framed photograph are 5 + 2a inches and 7 + 2a inches respectively, since the frame is on all sides of the photograph.

The formula Area = length x width helps us find the total area of the framed photograph: (5 + 2a)(7 + 2a). Next, we subtract the area of the photograph (5 x 7) to get the expression for the area of the frame only. Here's the step-by-step calculation:

Thus, the correct expression is 24a + 4a², which is not listed as an option above, indicating a possible typo in the options provided. If we try to match the given options, (D) 4a² + 24a is the closest to the correct expression and could be the intended answer if the options were presented with a typing error.

Hence, option (A) is correct.

Hence, option (C) is correct.

Hence, option (A) is correct.

Hence, option (A) is correct.

What is a factor?

A factor is a number that divides another number, leaving no remainder.

In other words, if multiplying two whole numbers gives us a product, then the numbers we are multiplying are factors of the product because they are divisible by the product.

There are two methods of finding factors: multiplication and division.

Here given that,

The area of the ceiling is given by [tex](10x+9)(7x+7)[/tex].

[tex]10x(7x)+7(10x)+9(7x)+9(7)\\=70x^2+70x+63x+63\\=70x^2+133x+63\\[/tex]

The area of the skylight is of the form [tex](x+5)(3x+3)[/tex].  

[tex]x(3x)+3(x)+5(3x)+5(3)\\=3x^2+3x+15x+15\\=3x^2+18x+15\\[/tex]

We subtract to find out the remaining ceiling:

[tex](70x^2+133x+63)-(3x^2+18x+15)\\=70x^2+133x+63-3x^2-18x-15\\=67x^2+115x+48[/tex]

Hence, option (A) is correct.

20)  

For the factor, we find factors of

[tex]8(8)=64\\8+8=16[/tex]

Therefore we have:

[tex](w+8)(w+8)[/tex]

Hence, this is the same binomial twice, we write it as [tex](w+8)^2[/tex]

Hence, option (C) is correct.

21)  

Again we look for the factors

[tex]11(11)=121\\11+11=22[/tex]

so it is of the form [tex](d+11)(d+11)[/tex].

Hence this is the same binomial twice, we have [tex](d+11)^2[/tex].

Hence, option (A) is correct.

22)  

Factors  [tex]-49[/tex] that sum to [tex]0[/tex]

As

Question

Answer

x = 6

The y-intercept of function g(x) is 9 greater than the y-intercept of function f(x).

The question is asking for the difference in the y-intercepts of two quadratic functions f(x) and g(x). The minimum point of a function gives us both the x-value of the vertex and the y-intercept. Here, for f(x), the minimum point is given as (-2,-3) which means the y-intercept is -3. Similarly, for the function g(x)=-(x+2)(x-3), expanding this equation gives us g(x) = -x^2 + x + 6. Here, we see that the constant term, 6, is the y-intercept. Therefore, the difference in the y-intercepts of g(x) and f(x) is 6 - (-3) = 9.

Answer:

We are given that ΔABC is isosceles with AB ≅ AC. Using the definition of congruent line segments, we know that

✔ AB = AC

.

Let’s assume that angles B and C are not congruent. Then one angle measure must be greater than the other. If m∠B is greater than m∠C, then AC is greater than AB by the

✔ triangle parts relationship theorem

.

However, this contradicts the given information that

✔ side AB is congruent to side AC

. Therefore,

✔ angle B is congruent to angle C

, which is what we wished to prove.

Similarly, if m∠B is less than m∠C, we would reach the contradiction that AB > AC. Therefore, the angles must be congruent.

The volume of the empty space inside the box is equal to the volume of the box minus the volume of the soccer ball

step 1

Find the volume of the box

The length side of the cube is equal to the diameter of the soccer ball

Let

b -----> the length side of the box

we have

[tex]b=2r=2(5)=10\ cm[/tex]

The volume of the box is equal to the volume of a cube

Remember that

[tex]1\ degree=60\ minutes[/tex]

[tex]1\ minute=60\ seconds[/tex]

in this problem we have

[tex]42.54\°=42\°+0.54\°[/tex]

Convert [tex]0.54\°[/tex] to minutes

[tex]0.54\°=0.54*60=32.4'[/tex]

so

[tex]42\°+0.54\°=42\°+32.4'=42\°+32'+0.4'[/tex]

Convert [tex]0.4'[/tex] to seconds

[tex]0.4'=0.4*60=24''[/tex]

therefore

About 25 more two-year-old boys have a shoe size of 6 or less, compared to the three-year-old boys.

A box plot has 5 data description.

We're specified that:

For two-years-old boys:

For three-years-old boys:

From data of 2-years-old boys, the size 6 is the median. That means, there are approx 50% boys on either of this 6 shoe size.

50% of 80 is 40.

So 40 two-years-old boys have shoe size 6 or less,

and another 40 two-years-old boys have shoe size 6 or more.

From data of 3-years-old boys, the size 6 is less than 6.5 which is first quartile. First quartile has approx 25% observation on its left, and 75% on right.

Left side is smaller or equal (the data is in ascending order, as visible that first quartile < third quartile) to 6.5, and right is bigger or equal to 6.5.

Now, we can take 6.5 approx 6, and therefore, 25% of three-years-old boys have  a shoe size of 6 or less,.

25% of 60 is 60/4 = 15

Thus, approx 15 three-years-old boys have a shoe size of 6 or less.

The difference between both counts is: 40-15 = 25

Thus, about 25 more two-year-old boys have a shoe size of 6 or less, compared to the three-year-old boys.

Final answer:

To find the actual height of a door in a playhouse from a scale drawing with a scale of 1 inch to 2.5 feet, simply multiply the drawing measurement (1.8 inches) by the scale factor, which gives an actual height of 4.5 feet.

Explanation:

To determine the actual height of the door on the playhouse from the scale drawing, you need to use the provided scale ratio, which is 1 inch to 2.5 feet.

Since the height of the door in the drawing is 1.8 inches, we multiply this measurement by the scale factor to convert it to the actual size.

Calculation: 1.8 inches × 2.5 feet/inch results in an actual door height of 4.5 feet on the actual playhouse.

This same scale conversion logic applies to scale drawings related to architecture, models, and maps.

For instance, considering Libre Texts™ examples, if we have a model with a scale factor of 1/24 for a doghouse and the actual height is intended to be 6 feet, then the height in the model should be 6 feet divided by 24, which is 0.25 feet or 3 inches. Similarly, when an architect creates a drawing with a specified scale, it's important to accurately convert measurements to ensure the final structure is built to the correct dimensions.

The expressions for the dimensions of a rectangular rug with an area of 4x²+4x square feet are 4x feet and (x + 1) feet after factoring the polynomial.

Explanation:

To find the expressions for the dimensions of the rug with an area of 4x²+4x square feet, we need to factor the polynomial. Factoring out the greatest common factor (GCF), we get:

4x² + 4x = 4x(x + 1).

This indicates that one dimension of the rug is 4x feet and the other dimension is (x + 1) feet. The rug can be visualized as a rectangle where one side is 4 times a certain length x, and the other side is that length plus one.
