Answer:
(7x+2)(3x-1); (5x+4)^2 or (5x+4)(5x+4);
Step-by-step explanation:
formula to find area is L* W = A ; meaning length multiplied by width equals to the area.
21.
using the formula to find area...
l*w=a
(7x+2)(3x-1) would be your answer
btw, don't put the "=a" at the end, since it's an expression :))
22.
since the problem states that it's a square, you can just say either...
(5x+4)^2 or (5x+4)(5x+4) not sure which one your teacher accepts
Your answer is 7/8 bc 3+4=7
Remember that parentheses come first. Follow PEMDAS
Answer:
m=2/3.
Step-by-step explanation:
the equation for slope is y=mx+b, where m is slope. So, 2/3 is your slope.
Answer:
The value of car after 14 years is $ 2,363.04
Step-by-step explanation:
Given as :
The price of new car = N = $ 18,000
The rate of depreciation of the value of the car = R = 13.5 % per year
Let The value of car after 14 years = $ x
The time period = 14 years
<u>Now, According to question</u>
The value of car after n years = initial value of car × 
or, $ x = N × 
or, $ x = $ 18,000 × 
Or, $ x = $ 18,000 × 
∴ x = $ 18,000 × 0.13128
I.e x = $ 2,363.04
So, The value of car after 14 years = x = $ 2,363.04
Hence The value of car after 14 years is $ 2,363.04 Answer
