The formula for area of a triangle is A = bh/2, where b is the base length and h is the height of the triangle. For this triangle, the base is twice as big as the height; the base and height are represented as follows.

Height: h
Base: 2h

The area of the triangle is 64. Plug all values and expressions accordingly into the formula for area and solve algebraically for h.

A = bh/2
64 = 2h(h)/2
64 = 2h²/2
64 = h²
8 = h

b = 2h
b = 2(8)
b = 16

Answer:
The height of the triangle is 8 units and the base is 16 units.

7x+3y=m (solve for y)

allochka39001 [22]

Lets solve for y

7x+3y=m

Step 1: Add -7x to both sides.

7x+3x+-7x=m+-7x

Step 2: Divide both sides by 3.

$\frac{3y}{3}$ = $\frac{m-7x}{3}$

y= $\frac{1}{3}$ m + $\frac{-7}{3}$ x
