The answer is 20 to your question
Answer:
5. 7(x - 2) + 1 = -34
7x - 14 + 1 = -34
7x - 13 = -34
7x = -34 + 13
7x = -21
x = -21/7 = -3
6. 10x + 4 - 8x = 2(x - 1)
2x + 4 = 2x - 2
Cancel 2x means this equation has no solution
8. 5(x - 3) + 1 = 5x - 14
5x - 15 + 1 = 5x - 14
5x - 14 = 5x - 14
5x - 5x = -14 + 14
0
9. 2x + 3 = 5x + 3 - 3x
2x + 3 = 2x + 3
2x - 2x = 3 - 3
0
11. x + 2x + 1 = 3x + 5
3x + 1 = 3x + 5
Cancel 3x means this equation has no solution
12. -3 = -2x + 4/-4
-3 × (-4) = -2x + 4
12 = -2x + 4
12 - 4 = -2x
8 = -2x
8/-2 = x
-4 = x

46
Just add the 4+2= 6 and 2+2= 4 and flip, so 46 is the final answer.
Answer:
x = 13sqrt(3) ft = 22.5 ft
y = 13 ft
Step-by-step explanation:
The triangle is a 30-60-90 right triangle.
The ratio of the lengths of the sides is
short leg : long leg : hypotenuse = 1 : sqrt(3) : 2
From the ratio above we see that the hypotenuse is twice the short leg.
The long leg is sqrt(3) times the short leg.
y = short leg
x = long leg
26 ft = hypotenuse
y = 26 ft/2 = 13 ft
x = 13 ft * sqrt(3) = 13sqrt(3) ft = 22.5 ft
