(2x-8)(7x+5)=0
2x-8=0
Divide both sides by 2
X-4=0
Add 4 to both sides
X=4
7x+5=0
Subtract 5 from both sides
7x=-5
Divide both sides by 7
X=-5/7
X=4, x=-5/7
Hope this helps :)
Answer:
It is reflection
Step-by-step explanation:
We know these three rules:
-a rotation followed by a rotation is a rotation
-a reflection followed by a reflection is also a rotation
-a rotation folowed by a reflection is a reflection
So we have: f3r3 is f (reflection)
f2 f is r (reflection)
r3 r is r
f2 r is f
r2 f is f
r1 f is f
So, r1r2f1r3f2f3r3 is reflection.
Given:
QSR is a right triangle.
QT = 10
TR = 4
To find:
The value of q.
Solution:
Hypotenuse of QSR = QT + TR
= 10 + 4
= 14
Geometric mean of similar right triangle formula:
Do cross multiplication.
Switch the sides.
Taking square root on both sides.
The value of q is 
.
Zero product states : if a * b = 0, then a = 0 and/or b = 0
(x - 3)(x + 6) = 0
x - 3 = 0
x = 3
x + 6 = 0
x = -6
so x = 3 and x = -6
