The expression (x+a)(x+b) can not be written as a(x+b) + x(x+b). Therefore, option A is the correct answer.
What is the distributive property?The distributive property states that an expression which is given in form of A (B + C) can be solved as A × (B + C) = AB + AC.
Using distributive property, we get
x(x+b)+a(x+b)
= x²+bx+ax+ab
= x²+x(a+b)+ab
The expression (x+a)(x+b) can not be written as a(x+b) + x(x+b). Therefore, option A is the correct answer.

Rebecca left her house and walked 2 blocks east. She turned and walked 5 blocks north to get to the library. If each block is 1/4 of a mile, how far is he direct route from Rebecca’s house to the library?
Rebecca's direct route from her house to the library is approximately 1.35 miles, calculated using the Pythagorean theorem with her eastward walk of 0.5 miles and northward walk of 1.25 miles (2 blocks east and 5 blocks north, each block being 1/4 mile).
To find the direct route from Rebecca's house to the library, we can use the Pythagorean theorem since the distance forms a right triangle.
First, we calculate the distance Rebecca walked east: 2 blocks * (1/4 mile/block) = 1/2 mile.
Then, we find the distance she walked north: 5 blocks * (1/4 mile/block) = 5/4 miles.
Next, we square both distances: (1/2)^2 = 1/4 and (5/4)^2 = 25/16.
Now, we add these squares together: 1/4 + 25/16 = 16/64 + 100/64 = 116/64.
Taking the square root gives us the direct route distance: √(116/64) ≈ √1.8125 ≈ 1.35 miles.
So, the direct route from Rebecca's house to the library is approximately 1.35 miles.

cougar park is shaped like a parallelogram and has an area of 1/16 sqaure mile. Its base is 3/8 mile. What is its height?
The area of parallelogram can be found using the formula:
[tex] Area = b* h [/tex]
Where b= base length and h= height.
We are given :
Area =1/16 square mile and
Base = 3/8 mile
Plugging the values in the formula to find height,
[tex] 1/16 = 3/8* h [/tex]
height = 1/6 mile
So height of parallelogram is 1/6 miles.

Suppose that the water level of a river is 34 feet and that it is receding at a rate of 0.5 foot per day. Find the slope,including units, and write a sentence to interpret the slope in detail. Write an equation for the water level, y, after x days. In how many days will the water level be 26 feet? Graph the equation
Explanation of slope, equation, and days to reach a specific water level in a river.
Explanation:Slope: The slope represents the rate of change in water level per day. In this case, the slope is -0.5 feet/day, indicating that the water level is decreasing by 0.5 feet each day.
Equation: The equation for the water level after x days is y = 34 - 0.5x.
Days to reach 26 feet: To find when the water level will be 26 feet, you can solve the equation 26 = 34 - 0.5x to get x = 16 days. Therefore, it will take 16 days for the water level to reach 26 feet.
The dimensions of a parallelogram are reduced by half of its original dimensions. Determine how the perimeter of the parallelogram will be affected by the change in the dimensions of the original parallelogram..
reduced by a factor of one-fourth
reduced by a factor of one-half
increased by a factor of two
increased by a factor of four
Answer:
reduced by a factor of one-half
Step-by-step explanation:
Let one side of the parallelogram be 'a'
and the other side of the parallelogram is 'b'
Therefore the perimeter of the parallelogram given by,
P = 2 ( a + b )
Now when the dimensions are reduced to half of its original dimensions.
Then,
one side of the parallelogram be a/2
and the other side of the parallelogram is b/2
Now the new perimeter will be
P = 2 ( a/2 + b/2 )
P = 2 { (a + b)/2 }
P = a + b
Thus this clearly shows that the perimeter is reduced to one-half of the original perimeter when the dimensions are reduced by half.
Garrick and Zan are measuring the heights of seedling plants for science class.
Use the drop-down menus to complete the statements about the measured heights and the actual heights of the plants.
CLEAR CHECK
Because Garrick's plant is... than Zan's plant, each millimeter of error results in a ....percent error.
Garrick's measurement was ... millimeters off and Zan's was... millimeters off, so Garrick's measurement was ... % off and Zan's was
Answer: Garrick's plant is shorter than Zan's plant.
Each millimeter of error results in a 11.11% percent error.
Garrick's measurement was 2 millimeters off and Zan's was 12 millimeters off.
Garrick's measurement was 20% off and Zan's was 12% off.
Step-by-step explanation:
Since we have given that
In case of Garrick's plant:
Actual height of his plant = 10 mm
Measured height of his plant = 8 mm
In case of Zan's plant :
Actual height of his plant = 100 mm
Measured height of his plant = 88 mm
So, clearly Garrick's plant is shorter than Zan's plant.
Difference in actual height of plants of Garrick and Zan is
[tex]100\ mm-10\ mm=90\ mm[/tex]
similarly, difference in measured heights of plants of Garrick and Zan is
[tex]88\ mm-8\ mm\\\\=80\ mm[/tex]
Percent error will be
[tex]\frac{90-80}{90}\times 100\\\\=\frac{10}{90}\times 100\\\\=11.11\%[/tex]
So, Each millimeter of error results in a 11.11% percent error.
Error in Garrick's plant :
[tex]Actual-Measured\\\\=10-8\\\\=2\ mm[/tex]
Percent error is given by
[tex]\frac{2}{10}\times 100\\\\=20\%[/tex]
Similarly,
Error in Zan's plant ;
[tex]Actual-Measured\\\\=100-88\\\\=12\ mm[/tex]
Percent error is given by
[tex]\frac{12}{100}\times 100\\\\=12\%[/tex]
Garrick's measurement was 2 millimeters off and Zan's was 12 millimeters off.
So, Garrick's measurement was 20% off and Zan's was 12% off.
What is the inverse function of a(b)=12•b+9/2
To find the inverse of the function a(b) = 12b + 9/2, swap 'a' and 'b', then isolate 'b' by subtracting 9/2 and dividing by 12. This gives the inverse function as a = (b - 9/2) / 12.
Explanation:To find the inverse of a function, you need to rearrange the equation so that the independent variable 'b' becomes the dependent variable. In your function, a(b) = 12b + 9/2, first you need to solve for 'b'. Here are the steps:
Swap 'a' and 'b' to get: b = 12a + 9/2 Isolate 'b' by subtracting 9/2 from both sides: b - 9/2 = 12a Divide both sides by 12 to solve for 'a': a = (b - 9/2) / 12
So the inverse function of a(b) = 12b + 9/2 is a = (b - 9/2) / 12.
