Answer:
19,8
105,7
144,84
304
Step-by-step explanation:
At first, 9) is not correct.
Formula for surface of parallelogram is
A=a*H
DONt divide with 2.
So the 9) is 19.8
10) A=15.1*7=105.7
11) A=14.2*10.2=144.84
12) A=20*15.2=304
Okayyy, so the answer is 7.830. Adding a negative number is the same as subtracting a positive number so you can rewrite it as d-5.004=2.826, then you will add 5.004 to 2.826 and for your answer you will get 7.830.
Parallel lines have the same slope. The equation of the parallel line is therefore:
y = x + b
Plug in the values you are given to find b:
2 = -3 + b
b = 5
5x-y=-8 | subtract 5x from both sides.
-y = -5x - 8 | divide both sides by -1
y = 5x + 8 Done.
