Answer:
2x^2+8x-10
Step-by-step explanation:
Given data
Width= (2x -2) ft
Heigth= (x + 5) ft
The area of the base is given as
Area= width * heigth
Area= (2x -2)* (x + 5)
open bracket
Area= 2x^2+10x-2x-10
collect like terms
Area= 2x^2+8x-10
Answer:
probability of picking white is 6/10
and probability of picking orange is 4/10
Step-by-step explanation:
so probability of picking 2 white and 3 orange will be 9/25 + 64/100 = 8/125
The expression is
5x + 5y
We are to prove that it is an odd integer when x and y are integers of opposite parity
First, we can assume
x = 2a (even)
y = 2b + 1(odd)
subsituting
10(a + b) + 5
5 [(2(a + b) + 1]
The term
2(a + b) + 1 is odd and the result of an odd number multiplied by an odd number is odd
Not 100% sure this is correct but this seems correct.
