Answer:
A - x=13
Step-by-step explanation:
Pythagorean theorem
base is 5 (10/2)
height is 12
5^2 + 12^2 = c^2
25 + 144 = 169
c = 13
The area of a triangle is calculated by multiplying the base and the height, then dividing that value by 2.
(1/2)bh
Answer:
y = 4 or y = 6
Step-by-step explanation:
2log4y - log4 (5y - 12) = 1/2
2log_4(y) - log_4(5y-12) = log_4(2) apply law of logarithms
log_4(y^2) + log_4(1/(5y-12)) = log_4(/2) apply law of logarithms
log_4(y^2/(5y-12)) = log_4(2) remove logarithm
y^2/(5y-12) = 2 cross multiply
y^2 = 10y-24 rearrange and factor
y^2 - 10y + 24 = 0
(y-4)(y-6) = 0
y= 4 or y=6
Answer:
F
Step-by-step explanation:
1m = 100cm
0.8m = 100*0.8 = 80cm
6*12 = 72ft²
The area of the trampoline is 72ft²
Hope this helps! :)
