Hello there!

In this problem we are trying to find the value of b in the given equation: 8 + 3b = -13. To do this, we have to isolate b.

The first step is to subtract 8 from both sides of the equation.

8 - 8 + 3b = -13 - 8

3b = - 21

Next, divide both sides of the equation by 3.

3b÷3 = -21÷3

b = -7

So, -7 is your final answer!

Since the constant has been moved to the left side, you can move on to the next step which is adding (b/2)² to both sides of the equation.

h² + 14h + (14/2)² = -31 + (14/2)²

Simplify the parenthesis and exponent.

h² + 14h + 7² = -31 + 7²

h² + 14h + 49 = -31 + 49

h² + 14h + 49 = 18

Factor the expression of the left.

(h + 7)(h + 7) = 18

Take the square root of both sides.

√(h + 7)(h + 7) = ± √9 • 2

(h + 7) = ± 3√2

h + 7 = ± 3√2

Subtract 7 from both sides.

You solutions are:

h = -7 + 3√2 → -2.7573 → -2.76

h = -7 - 3√2 → -11.2426 → -11.24

goblinko [34]
It’s 52 because there are two sides with 64 degrees (the bottom two sides) and you add those to sides together and subtract your combine angle of the bottom 2 sides by 180 degrees which is the degree of all triangles combine and get 52

PLEASE HELP <br> WILL GIVE BRAINLIEST AND 5.0 STAR RATING

Moving left subtracts from the x value the number you move.

In (2,9) the x value is the number 2

You move 1 unit to the left so subtract 1 from 2:

2-1 = 1

You will be at (1,9)
