Answer:
2(x-1)(x-4)
Step-by-step explanation:
Begin by dividing each term by 2 and pulling the 2 to the front.
This is a trinomial. Trinomials are three term algebraic expressions typically featuring variables to exponent powers. To break these trinomials down we factor them using the diamond method or GCF. The diamond method states that for a trinomial multiply a*c then find two numbers which multiply to this number and add to b. When you find those numbers, write them as
.
a=1, c=4
ac=4 and add to b=-5 which -1 and -4 satisfy
The factored form is 2(x-1)(x-4).
<span>Let the distance from A to the ends of the lake be w and r . From the given it appears that
w / sin 104 = 136 / sin 56 and r / sin 120 = 136 / sin 15....solve for w & r.
then L² = r² + w² - 2 r w cos 65 , where L = length of the lake...
