would it be seven ÷ by three
B. B+4
This should be right because if the brothers age is b and Jonna's age is 4 years older then it would be b+4
Answer:
x= 110
Step-by-step explanation:
Supplementary angles add to 180
Let x be the other angle
x +70 =180
Subtract 70 from each side
x+70-70=180-70
x = 110
Answer:
B. (2a +3b)(4a -c)
Step-by-step explanation:
Group the terms pairwise, then factor each pair.
... (8a² -2ac) +(12ab -3bc)
2a is a common factor in the first pair of terms; 3b is a common factor in the second pair of terms. We can factor those out.
... = 2a(4a -c) +3b(4a -c)
Then we see that (4a-c) is a common factor in the result. We can factor that out.
... = (2a +3b)(4a -c) . . . . matches selection B
You would write it as 25,000 or it would be 0.025
