Answer:
7w - 2
Step-by-step explanation:
you are subtracting w from 8w. Whenever there is a variable with no number beside it, it is an understood 1. so subtract 8w - 1w. This gives you 7w. then you move to the numbers with no variables. The 6 has a subtraction sign infront of it, which can be used as a negative sign. so -6 + 4 would be 2. therefore in whole, the answer would be 7w - 2. I do believe I am correct, but feel free to Comment if something should be corrected.
Answer:
C = 60pi cm or approximately 188.4 cm
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
C = 2* pi * 30
C = 60 pi
We can approximate pi by 3.14
C is approximately 60*3.14 or 188.4
I think it is C:(-4,-4) But then again, I am only in in grade 5 doing 7/8 grade math. Sorry if it is wrong!
