Answer:
42
Step-by-step explanation:
We know that 10x + 6y = 7, and so
6(10x + 6y) = 6(7) = 42
A^2 + b^2 = c^2
C is your hypotenuse or the longest side of the triangle; you plug in your values and solve for the missing side:
15^2 + b^2 = 17^2
225 + b^2 = 289
*-225 on both sides to get b by itself*
B^2 = 64
*to get rid of the ^2; you take the square root*
B = sqrt 64
B= 8 <— final answer

Answer:
use substitution
(5 x 7) - (3 x 8) + 11= 35 - 24 + 11= 22
Answer:
<h2>x = -2 or x = 4</h2>
Step-by-step explanation:
The zeros:
(x + 2)(x - 4) = 0 ⇔ x + 2 = 0 or x - 4 = 0
x + 2 = 0 <em>subtract 2 from both sides</em>
x = -2
x - 4 = 0 <em>add 4 to both sides</em>
x = 4
