The area of a triangle is 64 m² and its height is 16 m find the length of its base,

8m

Step-by-step explanation:

The area of a triangle is calculated by multiplying the base by the height and then dividing the answer by 2.

A = bh/2

We can use this as a formula to find the base by substituting in the given values:

64 = 16b/2

Multiplying both sides by 2 will get rid of the fraction and isolate the b term:

64x2 = 16b/2 x2

128 = 16b

Finally we divide both sides by 16:

128/16 = 16b/16

8=b

The base is 8m.

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

the answer is $42.96
