Answer:
-1=x
Step-by-step explanation:
You multiply the -3 into the (2-x). which gives you -6+3x=9x. Know you wanna get ride of the 3x so you subtract from both sides, which then gives you. -6=6x. From here were gonna need to get x by itself so you divide both sides by 6.
Which TWO expressions are equivalent to<em> </em><em>(x - y) </em>2/3 - 3/4 <em>(y-x)</em>

Answer:
Step-by-step explanation:
Use n = {1, 2, 3, 10}.
n^2 -5 = {1, 2, 3, 10}^2 -5 = {1, 4, 9, 100} -5 = {-4, -1, 4, 95}
The first three terms are -4, -1, 4.
The 10th term is 95.
Answer:
B 7
Step-by-step explanation:
Since the triangles are similar by AAA
We can use ratios to find the length x (which is PR)
5 15
-------- = ------------
x 21
Using cross products
5 * 21 = 15 *x
Divide each side by 15
5/15 * 21 = 15x/15
1/3 * 21 =x
7 =x
