The base of a triangle is 5 times the height. if the area is 490 square feet, then what is the height of the triangle, in feet?

14 feet

Step-by-step explanation:

The formula for finding the area of a triangle is given as :

Area = x base x height

Let the height be h , then the base is 5 times the height , that is the base is 5h.

Substituting into the formula , we have

490 = x h x 5h

490 = x

multiply through by 2

980 =

divide through by 5

196 =

Therefore :

h = 14

Therefore : the height is 14 feet

im sorry but no. i just need to answer for 50 poonts oof

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
