40:32 simplified will be 5:4
Both 40 and 32 have a common denominator of 8. When both numbers are divided by 8 you get 5:4
Answer:
<h2>7x² + 9x + 90</h2>
Step-by-step explanation:
(7x + 9)x + 90 <em>use the distributive property </em><em>a(b + c) = ab + ac</em>
= (7x)(x) + (9)(x) + 90
=7x² + 9x + 90
<=> cosx = +1/2 or cosx = -1/2;
cosx = +1/2 => x = +π/3 + 2kπ, where k is an integer or x = -π/3 + 2kπ, where k is an integer;
cosx = -1/2 => x = +2π/3 + 2kπ, where k is an integer or x = -2π/3 + 2kπ, where k is an integer;
9 x 8 = 72
do what’s in the parentheses first and then just multiply
