Answer:
20 degrees
Step-by-step explanation:
a triangle's angle sum is 180 degrees, so you would subtract 180-60=120 because angle q is 60 degrees less than 180. now add 40 to 120 to equal 160 then subtract 160 from 180 to equal 20 degrees
Y=mx+b
m=slope
pareaell lines have same slope
so if it is paralell to y=(1/2)x+8 ten the slope is 1/2
so
y=(1/2)x+b
find b
the point (-2,2)
x=-2 and y=2
sub
2=(1/2)(-2)+b
2=-1+b
3=b
y=(1/2)x+3 is the equation

Answer:
6x² + x - 12 = (2x + 3) (3x - 4)
Step-by-step explanation:
Factor 6x² + x - 12 by grouping
we need to rewrite the middle term as a sum of two terms whose product is (6* −12) = −72 and whose sum is 1
The middle term = x = 9x - 8x
6x² + x - 12
= 6x² + 9x - 8x - 12 Grouping the first two terms and the last two terms
= (6x² + 9x) + ( - 8x - 12)
From the first two terms take 3x as a common and from the two terms take (-4) as a common
= 3x ( 2x + 3) -4 (2x + 3)
Take (2x + 3) as a common
= <u> (2x + 3) (3x - 4)</u>
