Answer:
x = 3
Step-by-step explanation:
You can see that 5x - 7 and 2x + 2 are equal to each other due to the arrows pointing to both angles. Therefore allowing you to set up the following equation..
5x - 7 = 2x = 2
Therefore you can then simplify for the value x where you should get teh value 3.
The length is two inches less than five times the width. This means
Length (L) = 5w - 2. (Does this make sense? You calculate 5 times the width and then minus 2)
Then we know the perimeter of a rectangle is 2(L+w) so
Perimeter = 2(5w-2 + w) = 2(6w-2) = 12w - 4 (so C and D are both correct because they are equal)
We check the other two options manually,
A: 2(5w-2)+2w = 10w-4+2w = 12w - 4 (so A is correct because it equals D which also equals C)
B: w+w+5w+5w-2 = 12w - 2 (which does not equal any of the other options)
So correct answers are A, C and D because they are all equal.
Answer:
x = 9
Step-by-step explanation:
4x+5=41
To solve for x, we subtract 5 from each side
4x+5-5=41-5
4x = 36
Divide each side by 4
4x/4 = 36/3
x = 9
So the answer might be 61.0 because if you subtract (-)63.5 with 2.5 it would 61.0 so i dont know ..but good luck and if i fail you im so sorry
Answer:
h(0) = 10
h(4) = 16
Step-by-step explanation:
h(0) = 2(0)² - 3(0) + 10 = 10
h(4) = 2^4 = 16
