The Answer is -398
3^3 - 2(5)^2 - (5)^3
27-2(5)^2-3(5)^3
27-2(25)-3(5)^3
27-2(25)-3(125)
27-50-375
-398
2 ↔ exponent
5 ↔ coefficient
7 ↔ constant
x ↔ variable

Answer:
9/308
Step-by-step explanation:
The probability is the area of the square divided by the area of the rectangle.
p = (3 in.)² / (22 in. × 14 in.)
p = 9/308
Answer:
40%
Step-by-step explanation:
14 - 10 = 4
4/10 = 0.4
0.4 x 100% = 40%
Answer: 2 + √10 , 2 − √10
Step-by-step explanation:
-5x(x-4) = -30
divide by -5
x(x - 4) = -30
distribute the x
x^2 - 4x = 6
move the 6 to the left to have the equation equal zero
x^2 - 4x - 6 = 0
plug into the quadratic formula & solve
x
= 2 + √10 , 2 − √10
