Answer:
B
Step-by-step explanation:
Total segment bought=190+27=217 segments
Total length of the whole anchor=217*9/2=1953/2=976 1/2 meters
When multiplying the same base with exponents, you keep the base the same and then you add the exponents, so for this question you do:
10^3 x 10^6
10^9
Answer:
K 20
Step-by-step explanation:
f(x) = 7x2 - 4x
f (2) = 7 (2)^2 - 4(2)
= 28 - 8
= 20
Since they replaced the x inside f(x) with 2, just do that the same to the right side, change all x into 2
9514 1404 393
Answer:
8 m
Step-by-step explanation:
Using the given information, we know that ...
64 m^2 = A = s^2
(8 m)^2 = s^2
8 m = s
The length of one side of the room is 8 meters.
Answer:
Option 2
Step-by-step explanation:
First distribute 5r to 2r and 4 to get 10r^2+20r
Then distribute 8 to 2r and 4 to get 16r+32
After that you combine the like terms, so combine 20r and 16r to get 36r
Since there aren't other like terms for 10^2 and 32 you leave them how they are
After you combine your like terms you write the terms in order to get 10r^2+36r+32
Hope this helped!
