Answer:
a = 4 and b = - 30
Step-by-step explanation:
Expand the left side and compare like terms on both sides, that is
(x + 2)(x - 3)(x + 5) ← expand the first pair of factors using FOIL
= (x² - x - 6)(x + 5) ← distribute
= x³ + 5x² - x² - 5x - 6x - 30 ← collect like terms
= x³ + 4x² - 11x - 30
Compare like terms with x³ +ax² - 11x + b
4x² and ax² ⇒ a = 4
+ b and - 30 ⇒ b = - 30
Answer: 27a^3
It is 27a^3 because if you do 3×3=9 then 9×3= 27
The answer to the question is 1.
Length of hypotenuse (h) of 45-45-90 triangle with legs = 5sr3
The legs of a 45-45-90 triangle are equal since their opposite angles (45) are equal. The ratios for the sides of all 45-45-90 triangles is:
x, x, xsr2
