Assuming you can't simply put the number inside a calculator: write the number as a fraction:
Find the prime factorization both numerator and denominator:
The square root halves the exponents, so the number becomes
Answer:
- 13a - 85
Step-by-step explanation:
Given
- 5a - 86 - 8a + 1 ← collect like terms
= (- 5a - 8a ) + (- 86 + 1)
= - 13a + (- 85)
= - 13a - 85
6(x + 5)² - 5(x + 5)
6(x + 5)(x + 5) - 5(x) - 5(5)
6(x(x + 5) + 5(x + 5)) - 5x - 25 Distributive Property
6(x(x) + x(5) + 5(x) + 5(5)) - 5x - 25
6(x² + 5x + 5x + 25) - 5x - 25 FOIL
6(x² + 10x + 25) - 5x - 25
6(x²) + 6(10x) + 6(25) - 5x - 25
6x² + 60x + 150 - 5x - 25 Distributive Property
6x² + 60x - 5x + 150 - 25
6x² + 55x + 125 Adding Equations
6x² + 30x - 25x - 125
6x(x) + 6x(5) + 25(x) + 25(5)
6x(x + 5) + 25(x + 5)
(6x + 25)(x + 5) Factoring
She bought 24 cans. (8 were free)
Explanation:
32 cans divided by 4 (three cans and one free can). You then multiply the answer, 8, by 3, to get 24 cans that Tessera bought and 8 she got for free.
