Answer:
x = 4
Step-by-step explanation:

Multiply both sides of the equation by 3
7 + 2x = 15
Subtract 7 from both sides of the equation
2x = 8
Divide both sides of the equation by 2
x = 4

Answer:
323 feet
Step-by-step explanation:
This is basically the Pythagorean Theorem. If you have experience with this formula, you will know that it only works with right triangles. Why are we talking about a triangle when this problem speaks of rectangles? Well, this is because when a rectangle is split diagonally, it is now two separate triangles. The Pythagorean Theorem states that a^2 + b^2 = c^2. To begin, we will take the base and height of the triangle and either square root them or square them. In this case, you will need to square them. When this is done, you will have the numbers 90,000 and 14,400. What do we do with these? We will add them together now. Next, we will take the sum of these two numbers (104,400), and square root it. This leaves you with 323.109888, but, we need to round it to the nearest foot or, the nearest whole number. This will give us 323 feet as our final answer. Glad I was able to help! ;):)

STEP 1:
find the length of the sides of the square
AREA FORMULA (for a square)
x= side
A=x^2
225=x^2
take square root of both sides
15 feet= x
STEP 2:
find perimeter
PERIMETER FORMULA (for a square)
x= side of square
P= 4x
use x value from step 1
P= 4(15 ft)
P= 60 feet
ANSWER: The perimeter is 60 feet.
Hope this helps! :)
Answer:
Given - A triangle UTS
angle U = 43°
angle T = 103°
As we know that the side opposite to the largest angle is longest. angle T is longer so side opposite to it Us is longer
US , UT , TS
