Solve the equation and it will add up to -6 so
3×-7=-21
-21-10=-31
-31+25=-6
Answer:
<h3>or infinitely many</h3>
Step-by-step explanation:
simplifying the equation -6x + 8y = 12 dividing by 2 would give us the same equation as
-6 / 2x + 8 / 2y = 12/2
-3x + 4y = 6
Answer:
x = 40
y = 62
Step-by-step explanation:
I figured out the answer by finding the x on the left triangle first by writing an equation:
(3x - 18) + (x + 7) + (x - 9) = 180
once I worked that I plugged in the number which was 40.
Then for the triangle to the right I also plugged in the numbers for x and got 118 degrees I took 180 and subtracted 118 to get my answer of 62 for y.
(4x + 3y)² =
<span>(4x)² + 2 (4x) (3y) + (3y)² = </span>
<span>16x² + 24xy + 9y²</span>
