P square=P triangle equilateral
4(x+2)=3*2x
4x+4*2=6x
4x+8=6x
6x-4x=8
2x=8
x=8/2
x=4
Answer:
8 + 
Step-by-step explanation:
I'm assuming you want an answer to the top section of the question.
We can start with 8.
8
When a problem asks for the sum, it's looking for addition, so we use the + sign.
8 +
The problem says "a number," so let's represent that with x. Basically, x just means a number we don't know.
8 + x
The "number" is divided by 4, so we'll just put x/4 as our second term.
8 +
The ball hits the ground when the height h(t) = 0 , so
-16t^2 + 80t = 0
-16t(t - 5) = 0
t- 5 = 0 or -16t^2 = 0 ( here t = 0 which corresponds to when ball is thrown)
t - 5 = 0 gives:-
t = 5 seconds (answer)
1. 80 sheep when increase in the ratio 5:4 becomes 100 sheep.
2. The perimeter of the shape is : 26cm
<h3>What is Perimeter?</h3>
Perimeter is the outside boundary of a shape.
It is usually calculated by summing up all the length of the sides of that shape.
Analysis:
1. if the sheep is increased in the ratio 5:4
then new number of sheep becomes 5/4 x 80 = 400/4 = 100 sheep
2. The perimeter of the shape is the sum of all the sides of the shape = 7 + 4 + 10 +5 = 26cm

Answer:
yes.
honestly, I didn't really do all the math.
3 in 18 minutes, a little better than 3 in 20 minutes. that translates to 9 in an hour, with 6 minutes left over.
3 hours of that (3×9) is the 27. with 6 minutes per hour left over, for a total of 18 minutes.
the teacher has time to grade the tests, get a cup of coffee, and take a few minutes to wonder why she didn't go into an easier line if work.
