First you bring the x to one side so u subtract 4x from 7x and you get the new equation as -9=3x+12 then you just solve and you get x is equal to -7
Which triangle side lengths form a right triangle? Choose all that apply. 5, 6, 7 6, 8, 14 8, 15, 17 10, 12, 15 15, 20, 25 16, 1

Answer:
C. 8, 15, 17
E. 15, 20, 25
Step-by-step explanation:
You need to take the 2 smaller numbers as in 8 and 15 square it, so 8x8= 64 and 15x15= 225 and then add 64+225= 289 and 17x17=289 so 289=289 ✔
Again square 15 and 20, 15x15=225 and 20x20=400 add them 225+400=625
and 25x25=625 so 625=625 ✔
Hope this helped and good luck!
also on edge 2020
3x^3 x 4x^2 = 12x^5
3x^3 x 1 = 3x^3
2x^2 x 4x^2 = 8x^4
2x^2 x 1 = 2x^2
1x x 4x^2 = 4x^3
1x x 1 = 1x
12x^5 + 3x^3 + 8x^4 + 2x^2 + 4x^3 + 1x
Simplify
12x^5 + 7x^3 + 8x^4 + 2x^2 + 1x
Thus, answer is B
Hope this helps!
Answer:
-7
Step-by-step explanation:
-8 = (-1/4)(4) + b
-8 = -1 + b
b = -7
The answer is
225.5 m
because if you add all the numbers up then you would get 224.5
