a: 16

b: 7

Step-by-step explanation:

16²+7²=c²

256+49=c²

√305=√c²

17.5=c

$tan^-1(16/7)$ =66.4°

(138+66.4)-180= 24.4°

What is the solution to (x+6)(x+2)=60

Citrus2011 [14]

Distribute to eliminate the parenthesis

x^2 + 2x + 6x + 12 = 60

Combine like terms

x^2 + 8x + 12 = 60

Subtract 60 from both sides

x^2 + 8x - 48 = 0

Factor the equation

(x+12)(x-4)=0
x+12=0
x+4=0

x= -12 and -4

A rectangle has a length of 3x + 7 and a width of 2x. If the perimeter of the

Art [367]

Answer:

The length of the rectangle is 31.

Step-by-step explanation:

We have that the length (L) and width (W) are:

$L = 3x + 7$

$W = 2x$

The perimeter of the rectangle is given by:

$P = 2W + 2L$

$94 = 2(2x + 3x + 7)$

$94 = 10x + 14$

$x = 8$

Now, we can calculate the length of the rectangle:

$L = 3x + 7 = 3*8 + 7 = 31$

Therefore, the length of the rectangle is 31 units.

I hope it helps you!
