Step-by-step explanation:
Sample Response:<span> The value of </span>m<span> must be greater than the value of</span><span> n</span><span>. When you multiply the binomials, the middle term is the result of combining the outside and inside products. So, </span>bx<span> = –</span>nx<span> + </span>mx<span>, or </span>bx<span> = (–</span>n<span> + </span>m)x<span>. This means that </span>b<span> = –</span>n<span> + </span>m<span>. When adding numbers with opposite signs, you subtract their absolute values, and keep the sign of the number having the larger absolute value. Since </span>b<span> is positive, m </span><span>must have the larger absolute value</span>
Answer:
A) 1.5
B) x^2-23x+42 = (x-2)(x-21)
C) x=2, x=21
Step-by-step explanation:
a) 15 -2x / 3 = 4
15-2x = 12 (Times by three on both sides)
-2x = -3
x = -3/-2 = 3/2 = 1.5
b) x^2-23x+42
x^2-23x+42 = (x-2)(x-21)
c) x^2 -23x +42 = 0
x=2, x=21
(x-2) = 0 ⇒ x = 2
(x-21) = 0 ⇒ x = 21
