Step-by-step explanation:
131.58 --> 130.00
130.00 ÷ 10 = 13
13 = 10% of 130
13 x 2 = 26 (20% of 130)
The tip would be $26
<u><em>Answer: x=-17 and -17=x. *The answer should be the negative sign.*</em></u>
Step-by-step explanation:
subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.
a-c=b-c
subtract by 5 both sides of an equation.
x+5-5=-12-5
simplify.
12+5=17
17-5=12
17-12=5
x=-17 and -17=x
Hope this helps!
Thanks!
Have a great day!
a) false (89+89=178⁰ not acute!)
b) false (they could both be 90⁰ but this is the only angle that works)
c) what
d) false (92+92=184⁰ this is less than 360⁰)
can you please explain c ????
Answer:
A) 5x²(x^(8) - 16)
B) 5x²[(x⁴ + √16) • (x² + ∜16) • (x + (8√16) • (x - (8√16))]
Step-by-step explanation:
We are given the expression;
5x^(10) - 80x²
A) Since the expression is, 5x^(10) - 80x², the greatest common factor is 5x². So we will factorize that out.
So, we have;
5x²(x^(8) - 16)
B) The complete factorization of 5x²(x^(8) - 16) will be;
5x²[(x⁴ + √16) • (x⁴ - √16)]
Now, (x⁴ - √16)] can be broken than further into;
(x² + ∜16) • (x² - ∜16)
Also, (x² - ∜16) can be broken down into;
[(x + (8√16) • (x - (8√16))
So, our complete factorization gives us;
5x²[(x⁴ + √16) • (x² + ∜16) • (x + (8√16) • (x - (8√16))]
