(b) -2
Step-by-step explanation:
it is very important to start by finding the equation of the line then substitute in some values.
Answer:
Length=12 inches Width=6 inches
Step-by-step explanation:
X can stand for the width. 2x can stand for the length since it is twice the width. The perimeter would then equal 6x. 6x is equal to 36. Divide by 6 to isolate x. X equals 6 inches. So twice the width would be 12 inches.
Answer:
The answer is 104
Step-by-step explanation:
I’m guessing the shape is a triangle so if you have to angels you add them up and minus then from 180 what you get is your missing angle.
Firstly you would do 30 - 10 = 20, so their ages combined is 20, Laura has to be 15, and Luci has to be 5.
Second, 4 years ago, Peter was 15 and Sylvia was 5, and also in 5 years Sylvia will be 14 and Peter will be 24.
Hope this helps.
