5x+y2
=15+4
=19
So 19 is the answer.
Answer:
12
Step-by-step explanation:
We already found x in a previous problem.
x = 6
The right triangle on the right side with sides x and y is also a 30-60-90 triangle.
The hypotenuse is twice the short leg.
x = 6
y = 2x
y = 12
Step-by-step explanation:
Length of rectangle = 4 * 3.5cm = 14cm.
Perimeter of rectangle = 2(14 + 3.5) = 35cm.
Area of rectangle = 14 * 3.5 = 49cm².
By using y=mx+b you get y=-3/8x-17/8
