Based on the lengths, the cheerleaders' banner is scaled down by a factor of 4.
So, 44 ÷ 4 = 11.
For the perimeter, 156 ÷ 4 is 39.
For the area, you have to do A=bh
(Area = base × height)
The base (length) is 11 inches, multiply that by two to get 22 inches which is the amount for both lengths. If the total perimeter is 39, you have to subtract 22 from that to get the remaining inches which is 17.
17÷2= 8.5 inches. The height is 8.5.
Now you can plug them in
A=bh
A=(11)(8.5)
A=93.5 in^2
The final answer is:
Area = 93.5 in^2
Length = 11 in
Perimeter = 39 in
I hope that helps!
Two ways:
1) guess factors(trial and error)
2) use quadratic formula.
If you use this method then a = -3, b = -6 and c = -1
x = -b +/- [sqrt(b^2 -4ac)/2a]
substituting a, b, and c into our equation we get:
x = - (-6)+/- [sqrt ((-6)^2) - 4(-3)(-1))/2 (-3)]
x = + 6 +/- [sqrt (36 -4 (3)/-6)] if I didnt make a mistake in my signs
x = + 6 +/- [sqrt (36 -12)/-6)]
x = 6 +/- [sqrt (24)/-6] but sqrt 6 x sqrt of 4 = sqrt 24 hence
x = 6 +/- [ sqrt 6 x sqrt 4 /-6] that is:
x = 6 +/- [sqrt 6 x 2 /-6 ]
so x = 6 + [sqrt 6 x 2/-6] and x = 6 - [sqrt 6 x 2/-6]
Answer:
45
Step-by-step explanation:
When × by values higher than 100%, you divide the number by ten and add it to the number you are taking percentage of In this case, 15+30 = 45
