Answer:
- 2 and 12
Step-by-step explanation:
let the 2 integers be x and y , x > y , then
x - y = 14 → (1)
x + y = 10 → (2)
add the 2 equations term by term to eliminate y
2x = 24 ( divide both sides by 2 )
x = 12
Substitute x = 12 into (2)
12 + y = 10 ( subtract 12 from both sides )
y = - 2
As a check
x + y = 12 + (- 2) = 12 - 2 = 10
x - y = 12 - (- 2) = 12 + 2 = 14
xy = 12 × - 2 = - 24

Answer:
it equals 7
Step-by-step explanation:
Answer:
-2
step by step
(-3)^3-5(-3)+7-((2(-3)-3))
-27+15+7-(-6-3)
-27+15+7-(-3)
-27+15+7+3
-27+25
=-2
Answer:
7x + 14
Step-by-step explanation:
the first thing to do is expand the parentheses/brackets.
3(5x + 2) -2(4x - 4) will be
3(5x) + 3(2) -2(4x) -2(-4)
= 15x + 6 - 8x + 8
collect like terms
15x - 8x + 6 + 8 = 7x + 14
the answer is 7x + 14
