Answer:
<u>The answer is x = -2</u>
Step-by-step explanation:
Let's solve for x the equation -3(x+5)=-9, this way:
-3 (x + 5) = - 9
-3x - 15 = -9 (Solving the parenthesis)
-3x = -9 + 15 (Adding 15 at both sides)
-3x = 6
x = 6/-3 (Dividing by -3 at both sides)
x = -2
<u>The answer is x = -2</u>

Answer:
I think its a side of a triangle is bisected
Step-by-step explanation:
Hello :
<span>the numbers are : x , y
x - y = 4...1)
xy = 96...(2)
by (1) : x = y +4...(*)
subsct in (2) : (y+4) y = 96
y² +4y -96 = 0
(y² +2(2y) +2²) -2² -96 = 0
(y+2)² -100 =0
</span>(y+2)² <span>= 10²
y +2 = 10 or y+2 = -10
y = 8 or y = -12 ( refused : x is positif)
y = 8
</span>subsct in (*) : x = 8+4 = 12
<span> the numbers are : 12 and 8
12-8 = 4 and 12×8 = 96</span>
Answer:
11
Step-by-step explanation:
A square root is any number that is multiplies by itself to get a number.
11*11=121
