For the first problem, the triangle is equilateral. This means that all three sides will have the same length. So you need to find a value for x that makes all three of those statements equivalent. I believe you could find it using a system of equations... but it’s been a while so don’t quote me on that.
For the second, ce and de are equal. Set them equal to each other and solve for x. Then plug that x value back into the side lengths.
Answer:
I think the first one is 18 and I think the second one is the 3rd one

The answer is the morning temperature was 5 degrees above the afternoon temp.
Answer:
y = 
x + 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = , thus
y = x + c ← is the partial equation
To find c substitute (- 2, 3) into the partial equation
3 = - 
+ c ⇒ c = 3 + =
y = x + ← equation of line
