Answer:
We know that, a³ - b³ = (a - b)(a² + ab + b²)
Now,
- x³ - 27
- (x)³ - (3)³
- (x - 3)(x² + 3x + 9)
Therefore,
- <u>(x² + 3x + 9)</u> is the other factor.
Answer:
Line AB is Perpendicular to line CD
Line AB Parallel to line EF
Answer:
92
Step-by-step explanation:
angle a and b add up to 180 degrees
4x-20+2x+8=180
add like terms
6x+12=180
x=28
then substitute to get 92
Answer:
8
Step-by-step explanation:
We have, 25% × x = 200
or,
25
100
× x = 200
Multiplying both sides by 100 and dividing both sides by 25,
we have x = 200 ×
100
25
x = 800
If you are using a calculator, simply enter 200×100÷25, which will give you the answer.
So now that you have the original number you just need to find 1% of 800
1% of 800 is 8
