Answer:
40%
Step-by-step explanation:
36/90 integers are 1, so the experimental probability is ...
p(1) = 36/90 = 0.40 = 40%

area of rectangle=length×breadth=(2x+3)(3x+7)
=6x²+9x+14x+21=6x²+23x+21
Answer:
Step-by-step explanation:
8x^2 - 4x
4x(2x - 1)
GCF is 4x
Hello from MrBillDoesMath!
Answer: B
Remark: It is customary to use x^2, not x2, to indicate the square of x.
Discussion:
(4x + 3) ^ 2= ( 4x)^2 + 2 * (4x)(3) + 3^2 =
16 x^2 + 24x + 9
Thank you,
MrB
Add -5 to each side of the inequality:
-3 ≤ x + 5 ≤ 8
-3 - 5 ≤ x + 5 - 5 ≤ 8 - 5
-8 ≤ x ≤ 3
Since x is an integer, there are 12 possible solutions belonging to {-8, -7, ..., 1, 2, 3}. In the sum of these solutions, the integers -3 to 3 cancel out, and the rest give
-8 - 7 - 6 - 5 - 4 = -30
