Answer:
Step-by-step explanation:
Perimeter is found by adding together all the lengths of the sides. For us, that is x + (2x + 5) + (6x - 17) + (3x + 2). Now we will just combine like terms. We can also drop the parenthesis because they do nothing for us and mean nothing to the problem.
x + 2x + 5 + 6x - 17 + 3x + 2 becomes
12x - 10
Answer:
50.4 km (Answer B)
Step-by-step explanation:
From this information, we are able to create a proportion, 2cm/21km= 4.8cm/x km (x representing the actual distance). After cross-multiplying and simplifying, you get an answer of 50.4km. Hope this helps!
First lets put like terms together!
subtract 5 by both sides
Then we have to get x by itself, in order to do this we divide by 2
Answer:
f(1) = -7
Step-by-step explanation:
Step 1: Define
f(x) = -x² + x - 7
f(1) = x = 1
Step 2: Substitute and Evaluate
f(1) = -(1)² + 1 - 7
f(1) = -1 + 1 - 7
f(1) = -7
