Answer:
w = 7m
l =9 m
Step-by-step explanation:
Let w = width
l = w+2
A = l*w
63 = (w+2) * w
63 = w^2 +2w
Subtract 63 from each side
0 = w^2 +2w - 63
Factor
What 2 numbers multiply to -63 and add to 2
9*-7 = -63
9-7 = 2
0 = (w +9) ( w-7)
Using the zero product property
w+9 =0 w-7 =0
w = -9 w = 7
Since we cannot have a negative length
w=7
l =w+2 =7+2 = 9
Answer:
The volume is <u>1539.38</u>
Step-by-step explanation:
Answer:
The value of x = 15.75
Step-by-step explanation:
∵ PQ and LM are two chords in the circle and intersected outside the circle at point N
∴ NM × NL = NQ × NP
∵NM = 14 and NL = 14 + 22 = 36
∵ NQ = x and NP = 32
∴ 14 × 36 = x × 32
∴ x = (14 × 36) ÷ 32 = 15.75
You can use the pythagorean theorem.

Now lets write out what we know.
Shorter leg = x
Longer Leg = x + 7
Hypotenuse = x - 7

Now solve for x

x = 28
Since you know x = 28, which is the shorter leg, you can solve for the rest by just plugging in 28 where x is located. For instance, longer let is x + 7 so
28 + 7 = 35
