The formula for the area of a triangle is 1/2*b*h=a.
1/2*b*14=56
b*14=112
b=8
First, solve the parenthesis
Remember to follow PEMDAS, and the left-> right rule
12/3 = 4
4 x 2 = 8
8 + 3 = 11
11 - 7 = 4
Square the remaining number
4² = 4 x 4 = 16
16 is your answer
hope this helps
Isolate the x and the 2 from the top of the equation, then cancel those out from the bottom, then divide out the -1. after that you are left with -6x²+2x-4
The answer to this equation is 5.
Answer: x = 9
Step-by-step explanation: divide 2/3x by 2 and do that to both sides to get 1/3x = 3 then multiply by 3 to get the whole x. multiply on both sides to get x = 9.
