Answer:
y = x + 4
Step-by-step explanation:
For a line to be Parallel it has to have the same slope but different y intercept
Answer:
length = 2w - 3
l = length
w = width
2(length) + 2(width) = perimeter
2(2w - 3) + 2(w) = 60
6w -6 =60
w = 11
len = 2(11) - 3
Step-by-step explanation:
Answer:
Acute
Step-by-step explanation:
The Converse of the Pythagorean Theorem states that:
- If
then the triangle is acute. - If
then the triangle is obtuse. - If
then the triangle is right.
The side lengths 8, 14, and 15 are given. We can assume the hypotenuse (or c) is the longest side length, so it is 15.
It doesn't matter which order of the numbers are plugged in for a and b, so a and b will be 8 and 14.
Now we have to add 
and 
to see if the sum is greater than, less than, or equal to 15 (c).
Calculate the rest of the problem.
We have to find what 
is before we can make a decision using the Converse of the Pythagorean Theorem.
260 (
) is greater than 225 (
). This means that the triangle is acute because 
.
Answer:30
Step-by-step explanation:the perimeter is 26 and the length is 7 more than the width so you subtract 14 for both the sides of the rectangle from the perimeter and are left with 12 so you divide that by 4 for the 4 sides of the rectangle and get 3 so the width is 3 and the length is 10.
