The product of $7d^2-3d+g$ and $3d^2+hd-8$ is $21d^4-44d^3-35d^2+14d-16$. What is $g+h$?

Answers

Answer 1
Answer:g = 2  and h = -5

Step-by-step explanation:

To find the product with unknown values of variables, multiply the terms and equate the value to the given product.

[tex](7d^{2} - 3d + g)(3d^{2} + hd - 8)[/tex] = [tex]21d^{4} + 7hd^{3} - 56d^{2} - 9d^{3} - 3hd^{2} + 24d + 3gd^{2} + ghd - 8g[/tex]

[tex](7d^{2} - 3d + g)(3d^{2} + hd - 8)[/tex]     = [tex]21d^{4} + (7h-9) d^{3} + (3g-56-3h)d^{2} + (24+gh)d -8g[/tex]   ... (1)

Comparing eq(1) to the product given in question,

-8g = -1

g = 2

24 + gh = 14, sub g =2,

24 + 2h = 14

h = -5

Answers

Step-by-step explanation:

I hope this is what you need

PLEASE MAKE ME BRAINLIEST

-3 • x + 5y = 25
1 • 3x + 4y = 20

-3x -15y = -75
3x + 4y = 20

-11y = -50

divide both by -11y

which will equal y = 5



then you’ll do
x + 5(5) = 25
x + 25 = 25

subtract the 25’s

StartFraction 6 Over x EndFraction = StartFraction 15 Over 9 EndFraction
StartFraction 9 Over 6 EndFraction = StartFraction 15 Over x EndFraction
StartFraction 6 Over 15 EndFraction = StartFraction 9 Over x EndFraction

Answers

Given:

Given that the side AB is parallel to side DE.

The length of AB is 15 feet.

The length of BC is 9 feet.

The length of CD is 6 feet.

The length of DE is x feet.

We need to determine the proportion that solves the distance between D and E.

Proportion:

The proportion that solves the distance between D and E can be determined by the similar triangle property.

Thus, we have;

[tex]\frac{BC}{CD}=\frac{AB}{DE}[/tex]

Substituting the values, we have;

[tex]\frac{9}{6}=\frac{15}{x}[/tex]

Thus, the proportion that solves the distance between D and E is [tex]\frac{9}{6}=\frac{15}{x}[/tex]

Answers

Answer:

The height of the cup is 0.51 in.

The height of the cup is 4.59 in.

Step-by-step explanation:

The volume of the cylinder is [tex]\pi r^2 h[/tex]

Given that,

The volume of the cup is 14.4375 in³.

If the measuring cup has a radius of 3 in.

Then,

[tex]\pi r^2h=14.4375[/tex]

Plug r= 3 in.

[tex]\pi (3)^2h=14.4375[/tex]

[tex]\Rightarrow h=\frac{14.475}{9\pi }[/tex]

⇒h=0.51 in.

The height of the cup is 0.51 in.

If it has radius of 1 in.

Then,

[tex]\pi r^2h=14.4375[/tex]

Plug r= 1 in.

[tex]\pi (1)^2h=14.4375[/tex]

When calculating total gross pay, you should ___
A) use only your hourly wage
B)use your hourly wage and tips
C) use only your tips
D) use your hourly wage and tips minus any deductions

Answers

Final answer:

To calculate total gross pay, sum the hourly wage and tips earned. This sum represents the entire earnings before any deductions such as tax or social security are taken into account. Thus, option b is correct.

Explanation:

When calculating total gross pay, you should use your hourly wage and tips. The gross pay represents the total amount earned before any deductions, such as taxes or social security, are subtracted. To find the total gross pay, simply add the total amount of earned hourly wage to the amount received from tips.

For instance, if an employee receives $15 per hour and works for 8 hours and also earns $40 in tips, their gross pay for that day would be:

Hourly wage: $15/hour x 8 hours = $120

Tips: $40

So, the total gross pay would be $120 + $40 = $160 for that day.

So, option b is correct.

solve the inequality
|0.2x+6| <0.15

Answers

Answer:

- 30.75 < x < - 29.25

Step-by-step explanation:

Inequalities of the type | x | < a , always have solutions of the form

- a < x < a

Given

| 0.2x + 6 | < 0.15, then

- 0.15 < 0.2x + 6 < 0.15 ( subtract 6 from all 3 intervals )

- 6.15 < 0.2x < - 5.85 ( divide all intervals by 0.2 )

- 30.75 < x < - 29.25

Final answer:

To solve the inequality |0.2x+6| < 0.15, we split it into two separate inequalities and find that the solution for x is -30.75 < x < -29.25.

Explanation:

To solve the inequality |0.2x+6| < 0.15, we first consider the absolute value function. This means we are looking for values of x that make 0.2x + 6 less than 0.15 and greater than -0.15. We split this into two separate inequalities:

0.2x + 6 < 0.150.2x + 6 > -0.15

Solving the first inequality for x:

0.2x < 0.15 - 6
0.2x < -5.85
x < -5.85 / 0.2
x < -29.25

Solving the second inequality for x:

0.2x > -0.15 - 6
0.2x > -6.15
x > -6.15 / 0.2
x > -30.75

Therefore, combining the two inequalities, we find the solution for x is:

-30.75 < x < -29.25.

Twenty less than the product of 3 and a number is -29. What is the number?

Answers

The equation representing 'twenty less than the product of 3 and a number is -29' is 3n - 20 = -29. Solving for n, we find that n equals -3.

When solving the equation twenty less than the product of 3 and a number is -29, we can translate this into a mathematical expression as 3n - 20 = -29, where n represents the unknown number. To find the value of n, add 20 to both sides of the equation, which gives us 3n = -9. Dividing both sides by 3, we find that n = -3. Thus, the number we are looking for is -3.
