Answer:
Step-by-step explanation:
80 can be written as a product of 16 and 5.
Distribute the square root to both terms.
16 is a perfect square 4×4.
Solve for x over the real numbers:
6/x - 20 = 0
Bring 6/x - 20 together using the common denominator x:
-(2 (10 x - 3))/x = 0
Divide both sides by -2:
(10 x - 3)/x = 0
Multiply both sides by x:
10 x - 3 = 0
Add 3 to both sides:
10 x = 3
Divide both sides by 10:
Answer: x = 3/10
Answer:
f(x) = 2x² + 3
g(x) = x² - 7
( f - g)(x) = 2x² - x² +3 --7
= x² + 3 + 10
= x² + 10
Hope this helps.
I maybe wrong, but I think it is 14
Simplify both sides of the equation
(Do distributive property)
Add 6v to both sides
Subtract 67 from both sides
Divide both sides by -1
The interior triangles are similar, so the following ratio should hold true:
9 x
--- = ------ then x^2=144 and x=12 (answer)
x 16
