Can you try typing the problem instead of using voice to text. sorry I could not understand
Answer:
-4
Step-by-step explanation:
8+4y= -8
4y= -8 -8
4y= -16
divide both sides by the coeffient of the variable. in this case divide both sides by 4
y=-4
Answer:
--- radius
-- Length of the square
Step-by-step explanation:
Given

Solving (a): Find the radius (when it formed a circle).
The length of the wire represents the circumference (C) of the wire.
So, we have:

Make r the subject

Substitute 264 for C


Take
as 22/7




Solving (b): Find the side length (when it formed a square).
The length of the wire represents the perimeter (P) of the wire.
So, we have:

Make L the subject

Substitute 264 for P


It would be letter D - 3648.
The probability of winning is 0.76 and the probability of losing is 0.24.
In each simulation the probability of winning exactly one match is: P(win one match) = 2C1 x 0.76 x 0.24 = 0.3648
Multiply the result by 10,000 simulations to get the expected number of times that exactly one match is won.
10,000 x 0.3648 = 3648 times.
