Answer:
D
Step-by-step explanation:
the square root is between 14.1 and 14.2.
7.) (36+42) x 24 / 2 = 936
8.) (11+14) x 10 / 2 = 125
9.) 16 x 9 / 2 = 72
10.) 21 x 32 / 2 = 336
Complementary angles add to 90o
the other angle = x
the first angle = 3x - 4
x + 3x - 4 = 90
4x - 4 = 90
4x = 94
x = 94/4
x = 23.5
the first angle = 3*23.5 - 4 = 66.5
The solution set of -4(x + 3) ≤ -21 is x ≥ 2.25
<h3>How to graph the solution set?</h3>
The inequality is given as:
-4(x + 3) ≤ -21
Divide both sides by -4
x + 3 ≥ 5.25
Subtract 3 from both sides
x ≥ 2.25
This means that the solution set of -4(x + 3) ≤ -21 is x ≥ 2.25

Answer:
5
Step-by-step explanation:
move the terms 6x-4=16+2x
collect like terms 6x-2x=16+4
divide both sides 4x=20
x=5
