Answer:
64 ft^2
Step-by-step explanation:
(x+7)(x-2)=90
x^2-2x+7x-14=90
x^2+5x-104=0
factor
(x+13)(x-8)=0
x=-13
x=8 ft original square side
area=8x8=64
25.20/420= .06. 6% sales tax
It would be the last option, 4 miles east, 2 miles south and 2 miles east
For this case we have that the equation that describes the height is:

Where,
v: initial speed
c: initial height
Substituting values we have:

Then, to find the time, we use the quadratic formula:

Substituting values we have:

Rewriting:



We discard the negative root because we want to find the time.
We have then:


Answer:
D. 
Answer: Same-Side Interior Angles Theorem
Step-by-step explanation:
- Same-Side Interior Angles Theorem says that when two lines are parallel and a transversal intersects it , then the angles on the same interior side are supplementary.
We are given that Two parallel lines PQ and RS are drawn with KL as a transversal intersecting PQ at point M and RS at point N.
Angle QMN is shown congruent to angle LNS.
Also, angle QML and angle SNK are the angles lies on the same side of the transversal.
It means the measure of angle QML is supplementary to the measure of angle SNK [ By Same-Side Interior Angles Theorem ]
