Your answer is c, 12. The triangle is based on the ratio 1:2, so we know that the values for ΔV must be 2·(any given side). Thus, x=4 and y=8, so x+y=12. Hope this helps!

A pizza has a diameter of 14 inches what is the approximate circumference
Savatey [412]
To find the circumference of a circle you can use either of these equations
3.14 X Diameter or 2 X 3.14 X Radius. But in this case we will use the first one. So 3.14 X 14 = 47.6 so the circumference of this circle would be 47.6 inches.
                                                                 I hope this helps :)

Solve for x<br> X^2+6x+9=20
Masja [62]

Answer:

x = 1.47  or x = -7.47

Step-by-step explanation:

x²+6x+9=20

This is a quadratic equation

x²+6x+9-20=0

x²+6x-11=0

Step 1 : Write the quadratic formula

x = <u>-b±√b²-4(a)(c)</u>

              2a

Step 2 : Substitute values in the formula

a = 1

b = 6

c = -11

x = <u>-6±√6²-4(1)(-11)</u>

              2(1)

x = <u>-6±√80</u>

          2

x = -3 + 2√5 or x = -3 - 2√5

x = 1.47         or x = -7.47
