Answer:
y = -3/2 + 7
Step-by-step explanation:
The line crosses the y-axis at 7. Meaning b is 7. the line goes down by 3 and to the right by 2, so the slope is -3/2

The base of each triangle is 11 ft, and the height of it is 9 ft.
And then, there are 4 of these triangles. So, as we know, when we do the formula for finding one triangle, we do 
. But if we have to do it for 2, then we will do... 
, and applying that same trick, if we have to do it for 4 of them, we will do

12 would be right since 3-12 would be 9 then 9 times 2 is 18.
Answer:
No
Step-by-step explanation:
Using the given values, 25 is the largest value, so if this were a right triangle, it would be the hypotenuse.
Using Pythagoras' theorem: For this triangle to be a right triangle, √(21² + 14²) must be equal to 25.
√(21² + 14²) = 25.239 (5sf) ≠ 25
Hence the triangle formed is not right.
Answer:
4
Step-by-step explanation:
The theorem is a+b=c.
So 6+?=10
And that is 4 because 6+4 is 10.
