Answer:
Step-by-step explanation:
log3^(2x+3) = log243
(2x+3)log3 = log243
2x+3 = log243/log3
2x = (log243/log3)-3
x = [(log243/log3)-3]/2
x = (5-3)/2
x = 2/2
x = 1
Check:
3^2(1)+3 = 243
3^2+3 = 243
3^5 = 243
3×3×3×3×3 = 243
9×9×3 = 243
81×3 = 243
243 = 243
Answer:
<h3>sin(x) = StartFraction 9 Over 15.2 EndFraction</h3>
Step-by-step explanation:
From the triangle given;
The length of hypotenuse FG = 15.2 meter
Since FE is the side facing the angle FGE, then;
the length of FE is opposite = 9 meters
m<FGE = x
According to SOH CAH TOA
sin theta = opp/hyp
sin m<FGE = FE/FG
Substitute the given values
sin x = 9/15.2
Hence the correct answer is sin(x) = StartFraction 9 Over 15.2 EndFraction
Answer:
4(2x - 5)
Step-by-step explanation:
Rewrite "20" as 4 * 5
Rewrite "8" as 4 * 2
=4 * 2x - 4 * 5
Factor out common term "4"
=4(2x - 5) <------ Your answer.
Most of those are correct but the ones that are not are, (15+8 divided by 4-6) as division comes first. 6x3-8 as multiplication comes before subtraction. And 2/3+4x2, multiplication comes before addition. So change those couple up and you got it.
