Answer:
9.64ft
Step-by-step explanation:
Since the diagram tends to form...a right angled triangle....;
with PR = 17ft...,PQ = 14ft
then to calculate the length of QR
we use the pythagoras theorem...which is only applicable to right angled triangles
PR^2 = PQ^2 + QR^2
(17)^2 = (14)^2 + QR^2
where we make QR the subject of formula;
QR^2 = (17)^2 - (14)^2
QR = square root of( 289 - 196)
QR = square root of( 93)
;Therefore the length of QR = 9.64ft
Answer:
Width: 10.5 feet
Length: 31.5 feet
Step-by-step explanation:
Let x represent width of the concrete slab.
We have been given that the length of a concrete slab is three more than three times the width. So length of the slab would be 
.
We are also told that the area of slab is 330 square feet. We can represent this information in an equation as:
Now, we will take square root of both sides.
Therefore, the width of slab is approximately 10.5 feet.
The length of the slab would be 
.
Therefore, the length of slab is approximately 31.5 feet.

Answer:
8x-24
Step-by-step explanation:
We open parenthesis, so we get:
6x-21+2x-3
Then, simplify by adding like terms:
8x-24 is your answer :)
