Answer:
19d + 11
Step-by-step explanation:
7(d + 2) - 3 (1- 4d)
Expand the brackets.
7d + 14 - 3 + 12d
Add or subtract like terms.
7d + 12d + 14 - 3
19d + 11
Answer:
C and D
Step-by-step explanation:
Let's add this all together.
9x + 5y + x - 3y
Combine like terms 5y + -3y and 9x + x
10x + 2y
So we know D is at least correct.
What else? C is also correct, because we can expand it outward.
10x + 5y - 3y = 10x + 2y
A and B are not correct! We can't multiply the ys or the xs.
B. Do you see how there is a pi symbol next to 308, that means you don't have to multiply by pi so 967.61 but divided by
Answer: -32
Explanation:
Use the graph when it is referring to f(x) and g(x) to find those answers.
-8 * 1 + 4 * -6 = -32
