Answer:
Step-by-step explanation:
So for the first one 8x is similar to -2x so you put them together and get 6x and posiative 17 and -9 are similar so you put those together and get 8 so the first eqaution is 6x+8 and for the second one 7y and 10y are similar also know as like terms so you put those together and get -3y becuase the seven is before the 10y and so the equation is -3y+11
For "<span>6x-(4-×)<17", the answer would be x = 3.</span>
<span>Based on Pythagoras’s Theorem:
x^2 + (x+2)^2 = 10^2
2x^2 + 4x + 4 = 100
X^2 + 2x -48 = 0
(x + 8)(x - 6) = 0
Solving for x = 6, the sides are 6m and 8m.</span>

all u have to do is find the rose over run and then plug it in
The sine ratio that was applied in step 2 is incorrect, therefore, the first error is in: B. step 2.
<h3>How to Apply the Sine Ratio?</h3>
The sine ratio that is applied when we want to solve a right triangle is, sin ∅ = opposite length / hypotenuse length.
In step 2, the sine ratio applied is wrong because:
- ∅ = W
- Opposite length = XZ
- Hypotenuse length = y
Thus, we should have:
sin(W) = XZ/y
The first error is in: B. step 2.
