Ok so I like to go in steps with these questions- first draw a picture and identify your variables.
W=width
L= 3w-1
Now we know that length times width gets us area so we plug in our variables into the area equation.
200 = w(3w-1)
When you foil that equation you end up with a quadratic : 3w^2-w-200 = 0
Either factor that or use the quadratic formula to get
w= 8.33 and w= -8
Since you can't have a negative dimension you need to use 8.33 and plug it back into your length equation.
Final answer:
w= 8.33ft
l= 23.99ft
*Now I simplified the decimals a little bit so you end up with 199.8ft^2 for the area so just add a few decimals on here and there*
1.15¹⁰=4.0456, the growth rate, so the increase is 3.0456 or 305%.
Answer:
Only area of PQR can be calculated.
Step-by-step explanation:
In PQR, we have both the base (24 cm) and the height (15cm) which is perpendicular to the base. Therefore using these two measurements, we can take
This is equal to 180 cm².
Answer:
A. The length is 3
B. angel T
C. The perimeter is 20ft
Step-by-step explanation:
They are congruent so there side leghths are the same.
