Answer:
2
Step-by-step explanation:
y would be the first number in the equation on the left side of the equal sign. This looks lik the y=mx+b formula, so m, being slope, would be 7, -3 would be x, and b would be 4.
Answer:
11 units.
Step-by-step explanation:
Rewrite it in the form a^2 - b^2, where a = 2x and b = 5
(2x)^2 - 5^2
Use the Difference o Squares: a^2 - b^2 = (a + b)(a - b)
<u>(2x + 5)(2x - 5) </u>
Answer:

Step-by-step explanation:
The side that is parallel to BC is EF
Find the slope of EF:

Easiest way is just put the formula in point-slope form and simplify.
Let's use point F, which is (6,2)

Simplify:

Add 2 on both sides:
