Answer:
4x+64
Step-by-step explanation:
Perimeter is the sum of all sides so you add all of the expressions together. Then combine like terms, x+x+2x, and 14+14+36. Combine them and you get 4x+64.
Answer:
A.
Step-by-step explanation:
$15 rental fee added to the 12.75 per hour. you have to multiply the 12.75 times the amount of hours rented, which we don't know yet so that's variable x. then he has only $45 to spend so it has to be equal to or less than that.
A =(b1+b2)h/2
actual b1 =10cm*10m/1cm =100m
actual b2 = 6cm*10m/1 cm = 60m
height = 5 cm*10m/1cm = 50m
A=(100+60)*50/2 = 160*50/2 =80*50= 4,000 m²

Answer:
#3: x is approximately 0.37, -5.37, #4: x is approximately 4.19, -1.19
Step-by-step explanation:
You can solve using the quadratic equation or by solving with the perfect square
= 
x is approximately 0.37, -5.37
Well, the X component (assuming x is the horizontal) is equal to RCosZ
Where Z is the angle and R is the size of the resultant
Substitute into formula :
X component = RcosZ
-3 = Rcos135°
R = -3/cos135°
R = 4.24264...
R = 4.24 (2dp)
The vertical component (or Y component) is equal to RSinZ
Vertical component = RSinZ
= 4.24264... × Sin135°
= 3
The answer is 3
