From the problem, we have an algebraic expression :

Which is the product of 1/4 and a number, plus 7.
ANSWER :
a. the product of one-fourth and a number plus seven
Y = -2x + 5 is parallel to line as the slopes ( = -2) are the same.
the other 2 lines are nether parallel or perpendicular
After carefully looking over my notes and gathering all my knowledge of college mathematics, I can honestly say that I have no idea what the answer is.
Answer:
x = 240
Step-by-step explanation:
Using the Altitude- on- Hypotenuse theorem
(leg of large triangle)² = ( part of hypotenuse below it) × (whole hypotenuse)
x² = 144 × 400 = 57600 ( take the square root of both sides )
x =
= 240
