Answer: x=-0.4
Step-by-step explanation:
Answer:
b = 24 ft
h = 10 ft
Step-by-step explanation:
120 = ½hb
120 = ½h(3h - 6)
240 = h(3h - 6)
240 = 3h² - 6h
80 = h² - 2h
0 = h² - 2h - 80
0 = (h - 10)(h + 8)
h = 10 ft or -8 ft
we ignore -8 as it makes no sense for a triangle side length.
b = 3(10) - 6 = 24 ft
The solution to –2(8x – 4) < 2x + 5 is x > 1/6
<h3>How to solve the inequality?</h3>
The expression is given as:
–2(8x – 4) < 2x + 5
Expand
-16x + 8 < 2x + 5
Evaluate the like terms
-18x < -3
Divide both sides by -18
x > 1/6
Hence, the solution to –2(8x – 4) < 2x + 5 is x > 1/6

D and E. An acute angle is any angle that is less than 90(a right angle). A is an obtuse angle(more than 90). And B + C are right angles. Hope this helps you!
