I need help please now
Arlecino [84]

Answer:

x=12

Step-by-step explanation:

This is an equilateral triangle.  That means all the angles are equal

There are three angles  and they add to 180.  180/3 =60.  Each angle is equal to 60

4x+12 =60

Subtract 12 from each side

4x+12-12 = 60-12

4x = 48

Divide by 4

4x/4 =48/4

x=12

the length of a rectangle is six inches more than width, if the preimeter of the rectangle is 24 inches find the length
Nostrana [21]

Answer:

Length = 9 inches

Step-by-step explanation:

The perimeter of a rectangle is:

perimeter = 2(length + width)

24 = 2(a+b)

a = b + 6

a = length

b = width

then:

24 = 2((b+6)+b)

24/2 = b+6+b

12 = 2b + 6

12-6 = 2b

6 = 2b

b = 6/2

b = 3 inches

a = b+6

a = 3+6

a = 9 inches

Check:

24 = 2(9+3)

24 = 2*12

Find the average rate of change between f(-7) and f(-1) in the function f(x)=x^2+2x -8
Levart [38]

Answer:

- 6

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

here [ a, b ] = [ - 7, - 1 ]

f(b) = f(- 1) = (- 1)² + 2(- 1) - 8 = 1 - 2 - 8 = - 9

f(a) = f(- 7) = (- 7)² + 2(- 7) - 8 = 49 - 14 - 8 = 27

Hence

average rate of change = \frac{-9-27}{-1-(-7)} = \frac{-36}{6} = - 6
