Step-by-step explanation:
Given
g(x) = - 2x² + 3x
g(3) = - 2 * 3² + 3 *3
= -2 * 9 + 9
= -18 + 9
= -9
0.56 as a percent is 56%.
Multiply 0.56 times 100 to get 56%.
400 in² = (20 in)²
The area of a square is the square of the side length.
The length of one of the sides is 20 inches.
A triangle with sides measuring 300, 400 and 700 because 300+400+700=1400 which is higher than the first triangle 300+400+500=1200
Answer:
x = 6
Step-by-step explanation:
Givens
There are 3 sides. All are equal to (4x - 3)
Their sum = 63
Formula
3(4x - 3) = 63
Solution
- 3(4x - 3) = 63 Divide by 3
- 12x - 9 = 63 Add 9 to both sides
- 12x = 63 + 9
- 12x = 72 Divide by 12
- x = 72/12
x = 6 Answer
