Answer: w=5 , L= 2+2(5)=12
Step-by-step explanation:
L=2+2W
A= 60
LxW=60, now we will replace the L
(2+2W)(W)=60 we multiply
2w^2+2w=60
2w^2+2w-60=0 we divide by 2 the equation so we can work easier
w^2+w-30=0
find out w using the quadratic equation
we will get 2 solution,
w=5 and another solution is -6, which is not valid, as the side can not be negative
Answer: x=−1 and y=4
Step-by-step explanation:
The answer is B. Natural numbers are {1,2,3,4...} so basically positive. Intergers consist of 0 so it can range from -#s to +#s
Answer:
The area of the resulting cross section is 
Step-by-step explanation:
we know that
The resulting cross section is a circle congruent with the circle of the base of cylinder
therefore
The area is equal to
we have
-----> the radius is half the diameter
substitute the values
Answr:
p=−7/2
Step-by-step explanation:
Simplify both sides of the equation.
p+
