Answer:
20
Step-by-step explanation:
4 + 2 + 5 + 4 + 0 + 1 + 1 + 3 = 20
Answer: - 25 < x < 5
Step-by-step explanation:The first thing is to Add 23 to both sides
The equation becomes
4 / x + 10 / < 37 + 23
4/x +10 / < 60
Divide through by 4
/ x +10/ < 15
to remove the modulus sign we have
-15< x + 10 < 15
we then solve one by one
firstly , - 15 < x + 10
subtract 10 from both sides
⇒ - 15 - 10 < x
-25 < x
solving the second part
x + 10 < 15
x < 15 - 10
x < 5
combining the two answers
-25 < x < x
<span>2cos^2x = sin2x
2cos^2x = 2sin x cos x
(2sin x cos x) / (2cos^2x) = 1
sin x / cos x = 1
tan x = 1
x = π/4</span>
A= a+b over 2 times height
18 + 8 = 26
26 divide by 2 = 13
13 x 6 = 78
area is 78
