Answer:
x= -2
Step-by-step explanation:
Answer:
L=25; W=17
Step-by-step explanation:
1. Create an equation
L+L+W+W=P -> (2w-9)+(2w-9)+(w)+(w)=84
2. Solve for W
a) Collect like terms
(2w-9)+(2w-9)+(w)+(w)=84 -> 6w-18=84
b) Move constant to the right
6w-18=84 -> 6w=102
c) Divide by 6
6w=102 -> w=17
3. Now plug in W to the L
2w-9=L -> 2(17)-9=L
a) Multiply
2x17=34 -> 34-9=L
b) Subtract
34-9=25 -> 25=L
There is not enough info, there si one thing about a pool and one about a park, but if i assume this is a typo, its 15/25 which can be reduced to 3/5, if i helped, plz mark me brainliest!
Step-by-step explanation:
With reference angle 30°
perpendicular (p) = 20
base (b) = x
hypotenuse (h) = y
Now
sin 30° = p / h
1 / 2 = 20 / y
y = 40
Again
cos 30° = b / h
√3 / 2 = x / 40
x =40 * √3 / 2
x = 20√3
Hope it will help :)
Hello. I do not know this answer on the spot. But there is an app called mymath and you can download it on any apple or android device that will give you the answer to any of the variables in the equation. Hope it helps
