Answer:

m=-6

Step-by-step explanation:

What you do is add 7 to both sides of the equation canceling the 7 out leaving you with -13+7 which is equal to -6 so, M=-6

hettie is stacking paper cups .each stack of 15 cups is 6 inches high. what is the total heightvof 10 stacks of cups ?

Maslowich

60 inches is the answer.

In this case the amount of cups do not matter only the height because that's what it's asking for.

If each stack is 6 inches we would have to multiply that by 10 because there are 10 stacks.

6 x 10 = 60 inches tall

Solve the following:<br> a. 4x^2 + 5x + 3 = 2x^2 − 3x<br> b. c^2 − 14 = 5c

Jet001 [13]

Answer:

(a) x = -0.418 , -3.581

(B) c = 6.855, -1.855

Step-by-step explanation:

(A) We have given equation $4x^2+5x+3=2x^2-3x$

$2x^2+8x+3=0$

On comparing with standard quadratic equation $ax^2+bx+c$

a = 2, b = 8 and c = 3

So roots of the equation will be $x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}=\frac{-8\pm \sqrt{8^2-4\times 2\times 3}}{2\times 2}=\frac{-8\pm 6.324}{4}=-0.418,-3.581$
