Answer:

The circumference of circle is 15.7 feet

Step-by-step explanation:

First, you have to find the radius of circle by dividing the diameter by 2 :

radius = diameter \div 2

radius = 5 \div 2

radius = 2.5 \: feet

Next, you have to substitute it into the formula of circumference, C = 2×π×r where r represents radius :

C = 2 \times \pi \times 5

let \: \pi = 3.14 \\ let \: r = 2.5

C = 2 \times 3.14 \times 2.5

C = 15.7 \: feet

Solve.<br><br> −7x = x2 + 12
adelina 88 [10]

Answer:

x = - 4 , x = - 3

Step-by-step explanation:

- 7x = x^2 + 12

Take all terms to one side of equation.

x^2 + 7x + 12 = 0

Find which 2 numbers multiply to give 12 and add to give 7.

a × b = 12

a + b = 7

a = 4

b = 3

Split the middle term using these 2 numbers.

x^2 + 4x + 3x + 12 = 0

Factorise each pair of terms separately.

x ( x + 4 ) + 3 ( x + 4 ) = 0

Bring out common factor of ( x + 4 ) and factorise.

( x + 4 ) ( x + 3 ) = 0

Using the Null factor law, make the expressions in each pair of parentheses equal 0.

x + 4 = 0

x = - 4

AND

x + 3 = 0

x = - 3

THEREFORE:

x = - 4 , x = - 3
