Answer:
b. 28x + 8y +2
Step-by-step explanation:
you need to distribute the -2 to all the numbers inside parentheses and then combine like terms.
-2*3x= -6x
-2*12y= -24y
-2*-5= 10 (remember neg times neg = pos)
-2*17= 34x
-2*-16y=32y
-2*4= -8
Now combine like terms
34x-6x= 28x
32y-24y=8y
10-8=2
Write the expression: 28x + 8y +2
(1,-2) Don’t really know how I can explain it to you but this is the answer...
Answer:
M = 70
Step-by-step explanation:
Supplementary Angles = 180
180 - 110 = 70
Also linear pairs = 180.
156
Step-by-step explanation:
90+24+y=180
114+y=180
-114 -114
y = 66
66 + 90 = 156
289 rounds up to 300
7 rounds up to 10
300 * 10 or 3000
