The answer is d=<span>= 1/2 (a+b) 2nd power </span>
100+30=130
130%=520
divide both sides by 13
10%=40
times 10 both sides
100%=400
original price is $400
Answer:
b. 15 square units
Step-by-step explanation:
We notice from the graph that AB is the hypotenuse of a right triangle 3 units wide and 6 units high. The Pythagorean theorem tells you the length of that will be ...
AB = √(3^2 +6^2) = √45 = 3√5
Similarly, altitude CD is the hypotenuse of a right triangle 4 units wide and 2 units high, so its length will be ...
CD = √(4^2 +2^2) = √20 = 2√5
The area is given by the formula ...
A = 1/2bh
A = 1/2(3√5)(2√5) = 15 . . . square units
Answer:
(12+2b)/12
Step-by-step explanation:
Answer:
x = 4
Step-by-step explanation:
distribute both parenthesis on the left side of the equation
6 + 3x - 2x - 1 = 9
x + 5 = 9 ( subtract 5 from both sides )
x = 4
