9. A triangle has an area of 36 yd2 and a base of 3 yd, what is the height of the triangle?

Step-by-step explanation:

The formula for a triangle's area is:

We know the area is 36 square yards and the base is 3 yards.

Substitute the values into the formula.

Divide by 1/2 or multiply both sides by 2.

We are trying to solve for the height, so we must isolate that variable. h is being multiplied by 3. The inverse of multiplication is division, so we must divide both sides by 3 yd.

The height of the triangle is 24 yards.

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
