What is the solution to the equation-3(h+5) +2 = 4(+6)-9?

h = -4

Step-by-step explanation:

Step 1: Distribute

-3h - 15 + 2 = 4h + 24 - 9

Step 2: Isolate x's

-15 + 2 = 3h + 4h + 24 - 9

-15 + 2 -24 + 9 = 3h + 4h

Step 3: Combine like terms

-28 = 7h

Step 4: Divide both sides by 7

h = -4

Alternatively, you can guess and check by plugging in each solution into the calc and seeing if it is correct or not.

A=base side= 12 cm3

B=base side = 18 cm3

C=base side= 24cm3

D=height= 48 cm3

Step-by-step explanation:

=1/4 *48

= 5019.386 cm3
