(X-7)(x+7)
Set each equal to zero
X-7=0 X+7=0
X=7 X=-7
Answer:
Step 1
Swap sides so that all variable terms are on the left hand side.
-2x-8=y−2x−8=y
Step 2
Add 88 to both sides.
-2x=y+8−2x=y+8
Step 3
Divide both sides by -2−2.
\frac{-2x}{-2}=\frac{y+8}{-2}
−2
−2x
=
−2
y+8
Hint
Undo multiplication by dividing both sides by one factor.
Step 4
Dividing by -2−2 undoes the multiplication by -2−2.
x=\frac{y+8}{-2}x=
−2
y+8
Hint
Undo multiplication.
Step 5
Divide y+8y+8 by -2−2.
x=-\frac{y}{2}-4x=−
2
y
−4
Hint
Divide.
Solution
x=-\frac{y}{2}-4x=−
2
y
−4
Step-by-step explanation:
yan po sana makatulong
I dont know if m2 is the variable or its suppose to be m(2)
Answer:
It's a isosceles triangle, i am not saying its clearly implied in the diagram with the red lines.... Which state that both the sides have same length
Hence if on ne side makes 55 with the base therefore the side with same length will make 55 with the base too
Hence its
55+55+x=180
X= 180-55-55
X= 70 degree
Therefore x is 70 degree
