Answer:
pls complete your question. what exactly are we supposed to calculate?
The answer is -6 ( 1-2m)
STEP BY STEP EXPLANATION:
Factor out the 2
2(1-2(-3m+2)
Distribute -2 through the parentheses
2( 1+6m-4)
Calculate the difference
2(-3+6m)
Factor out that -3
2 x (-3(1-2m)
Multiplying a Positive and a negative equals a negative!
-2 x 3 (1 - 2m) multiply:
-6 (1 - 2m) that’s the final answer
(mx + 7)(5x + n) = 5mx^2 + mnx + 35x + 7n
= 5mx^2 + (35 + mn)x + 7n
= px^2 + 15x + 14
7n = 14
n = 2
35+mn = 15
35+ m(2) = 15
35+ 2m = 15
2m = 15-35
2m = -20
m = -10
p = 5m
= 5(-10)
=-50
m(n + p) = -10(2 -50)
= 480
Answer:
n = 8
Step-by-step explanation:
2n - 5 = 11
2n = 11 + 5
2n = 16
n = 16/2
n = 8
