I mean, I don't know how to explain a generic way to solve this. Ask me about the specific train of thought if you are interested:
7 * 18 + 45 / 3 - 2 = 139
Answer:
(x -1)(12x +13)
Step-by-step explanation:
You are looking to rewrite the middle term as the sum of terms that have factors of (12)(-13) that have a total of +1. Those factors are -12 and +13, so the expression you are factoring by grouping is ...
12x^2 +13x -12x -13
= x(12x +13) -1(12x +13)
= (x -1)(12x +13)
40℅ is bigger because 1/5 as a percent is 20℅
Best Answer: <span> w1•d1 = w2•d2
150•`15 = 300 d2
2250 = 300 d2
d2 = 2250 ÷ 300 = 7.5 ft </span>
