Answer:

c = \frac{A}{12h} - b

Step-by-step explanation:

Okay, so the goal is to isolate c on one side with all the other terms on the other side. So, let's start by dividing both sides with 12h. After we do that, we will be left with \frac{A}{12h} = b+c. Now, we can subtract both sides by b, and we will be left with \frac{A}{12h}  - b = c. Yay! We've now isolated c and that is our final answer!

Hope this helped! :)

Explain relationship between the factors of a quadratic expression, the roots of the related quadratic equation, and the x-inter
Zinaida [17]

Step-by-step explanation:

So, let's use x2 - 3x - 28 as an example.

 

It's factors are (x - 7)(x + 4).

 

The roots are the x-values that make our expression equal 0. In order for x2 - 3x - 28 to equal 0, either of our factors need to equal 0, since 0 times anything is 0.

 

x2 - 3x - 28 = 0

(x - 7)(x + 4) = 0

 

x - 7 = 0

x = 7

(7 - 7)(7 + 4) = 0(11) = 0

 

x + 4 = 0

x = -4

(-4 - 7)(-4 + 4) = -11(0) = 0

 

That gives us two points on our graph, (7,0) and (-4,0). Where are those? On the x-axis! Thus, there are our x-intercepts.

 

By the way, for the future, along the x-axis, y = 0, so if you are asked for the x-intercepts (or roots), set y = 0 and solve for x.

 

Along the y-axis, x = 0, so if you are asked for the y-intercepts, set x = 0 and solve for y.

 

y = 02 - 3(0) - 28

y = -28

 

So, the y-intercept(s) of our same equation is y = -28, or (0,-28).

 

Boom.

Number 9 pleaseeeeeeeeeeeeeeeee
anzhelika [568]

Answer:

A) 5

Step-by-step explanation:

Since ABC and DEF are equal they will have the sum, you'll wanna plug in the numbers into the x spots on DEF. So instead of 4x-2, try 4(5)-2.

D and F:

4(5) = 20

20 - 2 = 18

A and C also equal 18

I hope this helps,

Kim multiplied 8 by 0.952 and got 76.16 how can you estimate to show that Kim's answer is incorrect
devlian [24]
Kim multiplied 8 by 0.952 and got 76.16 which is the wrong answer, the correct answer is 7.616. His mistake is about decimal point.
he is multiplying a number with a decimal number and decimal number have first digit less than 1 that is zero. In decimal number point is after zero so when you multiply that number with 8 the answer should have decimal point after first digit.
