In this problem, you combine the like terms...
4a - 3b + 7a
4a and 7a are like terms so you add them together.
4a + 7a = 11a
So, the answer is: 11a - 3b
For the shaded bit all you need to do is 8.5 × 6.
if you are to get the other bit then do 8.5 × 8
if it is to be both then just do that and add them together
Answer:2?
Step-by-step explanation:
Answer:
31.96
Step-by-step explanation:
The product of 2 numbers is simply one number multiplied by another
6.8 x 4.7 = 31.96
As a sanity check, just round the numbers off to a whole numbers and take a product of those two:
i.e 6.8 rounded off to the nearest whole number is 7 and 4.7 rounded off to the nearest whole number is 5.
7 x 5 = 35
If you look at the possible answers, only 31.96 is anywhere close to 35, hence you can be be more confident that your answer of 31.96 is correct.
