<span>√64=8
because 8*8 is 64 </span>
False. The 4 needs to be distributed to the terms in the parentheses, so the coefficient of x is 12.
Answer:
x=-1
Step-by-step explanation:
Step 1: Factor left side of equation.
(x+1)(x+1)=0
Step 2: Set factors equal to 0.
x+1=0 or x+1=0
x=−1
Answer:
x= -10
y= -4
Step-by-step explanation:
Given data
3x+1=8y----------------1
11y-3x=-11--------------2
rearange
3x-8y=-1------------------1
-3x+11y=-11---------------2
add 1 and 2
3x-8y=-1------------------1
-3x+11y=-11---------------2
0+ 3y= -12
y= -12/3
y= -4
put y= -4 in 2
11y-3x=-11
11(-4)-3x=-11
-44-3x=-11
-44+11=3x
-33= 3x
x= -33/3
x= -10
