Answer:
B
Step-by-step explanation:
When you look at the triangle look at the 3 vertices. Now look at you answers given and choose one that combines all 3 vertices. You don't want your answer to contain a letter/number that represents the length of a side.
So in this case you don't want M or Y in you answer.
Your answer has to be made up of A X andT.
The only answer that uses AXT is answer B.
Answer:
Step-by-step explanation:
-2x² + 12x + 32 = 0
discriminant = 12² - 4(-2)(32) = 400
positive discriminant means there are two distinct real roots
x = [-12 ± √(12² – 4(-2)·32)] / [2·(-2)]
= [-12 ± √400] / (-4)
= [-12 ± 20] /(-4)
= 8, -2
Answer:
<em><u>Using the mid-term break formula for all of them.</u></em>
a) x²+7x+12
= x²+3x+4x+12
= x(x+3)+4(x+3)
= (x+4)(x+3)
b) x²+6x+8
= x²+2x+4x+8
= x(x+2)+4(x+2)
= (x+4)(x+2)
c) x²+5x+6
= x²+2x+3x+6
= x(x+2)+3(x+2)
= (x=3)(x+2)
d) x²+8x+7
= x²+7x+x+7
= x(x+7)+1(x+7)
= (x+1)(x+7)
