(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:
the number is 1
Step-by-step explanation:
Your equation to solve is:
4 +3x = 7
move the four
4 + 3x = 7
-4 -4
3x = 3
x = 1
Answer:
y = 5
x = 10
Step-by-step explanation:
Remember your 30 60 90 triangle rules.
The 5√3 would equal x√3, so x would equal 5.
The x for the hypotenuse is 2x, so 2(5) is 10.
The y is the x for a 30 60 90 triangle, so y = 5.
Answer:
10 x 4 = 40, 40 x 2 = 80
5 x 10 = 50, 50 x 2 = 100
5 x 4 = 20, 20 x 2 = 40
100 + 80 + 40 = 220 ft2
