Answer:
2)
(2x -5) + (x) + (2x - 3) = 32.
5x-8 = 32.
ii) 5x-8=32
5x= 32+8
5x = 40
x= 40/5
x = 8
iii) 2x -5
2 × 8 -5 = 11.
2x-3
2×8-3
16-3 = 13
x =8
sides of the triangle= 8, 11, 13.
90/110 reduces to 9/11. Good luck!
Idk if this is what you’re looking for but here you go
Answer:
x = 3/2 or x = -5/4
Step-by-step explanation:
Solve for x over the real numbers:
8 x^2 - 2 x - 15 = 0
Using the quadratic formula, solve for x.
x = (2 ± sqrt((-2)^2 - 4×8 (-15)))/(2×8) = (2 ± sqrt(4 + 480))/16 = (2 ± sqrt(484))/16:
x = (2 + sqrt(484))/16 or x = (2 - sqrt(484))/16
Simplify radicals.
sqrt(484) = sqrt(4×121) = sqrt(2^2×11^2) = 2×11 = 22:
x = (2 + 22)/16 or x = (2 - 22)/16
Evaluate (2 + 22)/16.
(2 + 22)/16 = 24/16 = 3/2:
x = 3/2 or x = (2 - 22)/16
Evaluate (2 - 22)/16.
(2 - 22)/16 = -20/16 = -5/4:
Answer: x = 3/2 or x = -5/4
