Answer:
(x - y)(x + y)(x² + y²)
Step-by-step explanation:
- 
← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b), thus
-
= (x²)² - (y²)²
= (x² - y²)(x² + y²) ← x² - y² is also a difference of squares, then
= (x - y)(x + y)(x² + y²)
13x+26=91
13x+26-26=91-26
13x=65 (Divide)
x=5
Hope this helps!
Answer: 820
Step-by-step explanation:
41/0.05 = 820
At least means greater than or equal to.
10 × (15+b) ≥ 26
150+10b ≥ 26
10b ≥ -124
b ≥ -12.4
