Step-by-step explanation:
The exterior angles of an equilateral triangle will always have a measure of 120°.
Answer:
-2
this eq. can be simplified to -
y = 5 - 2x
we know that the coefficient of x is the slope
therefore , -2 is the slope
Answer:

Step-by-step explanation:
ummmmmm I'm done it's just that I can't do 20 words
Answer: 70.1
Step-by-step explanation:
For these kinds of expressions use FOIL (first, outside, inside, last).
-2x • 9x = -18x^2
-2x • -3y = 6xy
8y • 9x = 72 xy
8y • -3y = -24y^2
Now combine them all:
-18x^2 + 78xy - 24y^2
