Question

Factoring by grouping : 48x^y + 20xz + 12xy +5z

Answer 1

4x^2 + 20x + 5y +xy
=4x^2+20x+xy+5y
=4x(x+5)+y(x+5)
=(4x+y)(x+5)
.
48x^2y + 20xz +12xy + 5z
48x^2y+12xy+20xz+5z
12xy(4x+1)+5x(4x+1)
(12xy+5x)(4x+1)

what do you need help with ?

Answer 6

MODELING - Complementary Angles The difference between the measures of two complementary angles is 16°. Determine the measures of the two angles.

Answer 7

x+y=90
x-y=16
add them:
2x = 106
x = 53
Get y:
y = 90-53 = 37
They are 37 degrees and 53 degrees

Answer 8

thank you
