Step-by-step explanation:
remember, when you multiply 2 expressions, you need to multiply every term of one expression with every term of the other expression and then add the results up (while considering their individual signs, of course).
1)
2(s + 8) = -(4s + 2)
2×s + 2×8 = -4s + -2
2s + 16 = -4s - 2
6s + 16 = -2
6s = -18
s = -3
2)
-(8 - 7b) = 6(2 + b)
-8 - -7b = 6×2 + 6×b
-8 + 7b = 12 + 6b
-8 + b = 12
b = 20
3)
6(4x - 11) = 9 - x
6×4x - 6×11 = 9 - x
24x - 66 = 9 - x
25x - 66 = 9
25x = 75
x = 3
4)
-5(4 - x) = 2(-x - 3)
-5×4 - -5×x = 2×-x - 2×3
-20 + 5x = -2x - 6
-20 + 7x = -6
7x = 14
x = 2
5)
-6(y - 1) = 4(9 + y)
-6×y - -6×1 = 4×9 + 4×y
-6y + 6 = 36 + 4y
-10y + 6 = 36
-10y = 30
y = -3
6)
7(2s + 6) = 5(s - 6)
7×2s + 7×6 = 5×s - 5×6
14s + 42 = 5s - 30
9s + 42 = -30
9s = -72
s = -8
7)
z + 4 = 8(-z + 5)
z + 4 = 8×-z + 8×5
z + 4 = -8z + 40
9z + 4 = 40
9z = 36
z = 4
8)
-2(3 + 5x) + 3(1 - x) = 10
-2×3 + -2×5x + 3×1 - 3×x = 10
-6 - 10x + 3 - 3x = 10
-3 - 13x = 10
-13x = 13
x = -1
Answer:
That blood.dy idiot!!! I would slap that person, throw him out of my house and end the relationship with no regrets!!
When a square root of an expression is multiplied by itself, the result is that expression
-10 x 2 x 15
Calculate the product
-300
The answer is B. It is a result of the survey.
