4^2 + 5^2 = EK^2
16 + 25 =
41 = EK^2
EK = square root of 41
12 + 12 + square root of 41 + square root of 41 = perimeter
24 + 2(square root of 41)
About 36.8
Hope it's right
Firstly let’s assume she is correct and use an equal sign:
1/2(12x + 24) = 3(2x + 4)
Now simplify both sides:
1/2 • 12x = 6x
1/2 • 24 = 12
6x + 12
3 • 2x = 6x
3 • 4 = 12
6x + 12
And:
6x + 12 = 6x + 12
Therefore they are equivalent, she is correct.
Answer:
20 = 4 × 5
Step-by-step explanation:
The translation from English is straightforward. "is" means "=". "times" is usually represented by "×" or a raised dot (·).
20 is 4 times 5
translates to
20 = 4 × 5
Answer: 150 degrees
Step-by-step explanation:
<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>
