Solve the parentheses first;
The image of the number line is missing, so i have attached it.
Answer:
5 metres
Step-by-step explanation:
From the attached image, we can see that point A is at -2.5 while point B is at 2.5.
Thus,distance between points A and B is; 2.5 - (-2.5). Where -2.5 is the additive inverse of 2.5.
Minus outside bracket when multiplied by minus inside the bracket will yield a positive sign.. Thus: distance = 2.5 + 2.5 = 5 m
Answer:
264 sq. in.
Step-by-step explanation:
The easiest way to find the lateral surface area is to multiply the perimeter of the base times the height.
In your case the perimeter of the base is 2(8) + 2(3) = 16 + 6 = 22
The height is 12, so multiply 12 times 22 = 264 sq. in.
4:32 is the same as 2:16 and 12:96. A ratio is the same as a fraction, so you can reduce them the same way. 4/2 = 2, 32/2 = 16. 2*6 = 12, 16*6 = 96.
Can you do the second one on your own now?
