Answer:
x = 8
Step-by-step explanation:
The complete question illustrates that the rectangle has sides ABCD and I've represented it as an attachment.
We have that:
AB = 3x
AD = 7x
The perimeter is calculated as:
Perimeter = 2 * (AB + AD)
Substitute values for AB, AD and Perimeter
160 = 2 * (3x + 7x)
160 = 2 * 10x
160 = 20x
Divide both sides by 20
8 = x
x = 8
Answer:the odds is 60%
Step-by-step explanation:
because there are 2 dice with 6 sides on each and take the probability of rolling each out of 12 and you have your answer

Step-by-step explanation:
It's the Pythagorean theorem just relearn it and you should be fine
Answer:
575.4 sq inches
Step-by-step explanation:
you can divide this shape into:
13 x 13 square
trapezoid with bases of 13 and 30 with a height of 20
semi-circle with radius of 15
A(square) = 169
A(trapezoid) = 53
A(semi-circle) = 353.4
Answer:
9
Step-by-step explanation:
The formula to get the area of a triangle is A=
so all you have to do is work backwards. 18x2=36. 36/4=9.
