For every c substitute 4 and for every d substitute -2
c=4
d=-2
6c + 5d - 4c - 3d + 3c - 6d
= 6(4)+ 5(-2)- 4(4)- 3(-2)+ 3(4)- 6(-2)
=24+(-10)-16-(-6)+12-(-12)
=24-10-16+6+12+12
=28
Answer:
92
Step-by-step explanation:
92+88= 180 all suplementtary angles =180
The greatest common factor of 18 and 42 would be 2.
First problem:
n/4 + 2 = -9
-2 -2
n/4 = -11
x4 x4
n = -44
Check:
-44/4 + 2 = -9
-11 + 2 = -9
-9 = -9
Second problem:
3/4x = -12
0.75x = -12
-------- ----
0.75 0.75
x = -16
3/4 * (-16) = -12 OR 0.75 * (-16) = -12
-12 = -12
Still get the same answer.
