Answer: The perimeter is when you add all of the sides together, and the area is when you multiply the sides together
Step-by-step explanation:
Lets take a look at the options first.
option 1 and option 4 are not possible as (8x) (8x) would give us 64x^2, which is not what we want.
we’re left with option 2 & 3. when expanded, option 2 will look like :
16x^2 - 40x - 10x + 25
= 16x^2 - 50x + 25
however, we do not want the 50x. so the answer is option 3, (4x-5) (4x+5)
if you don’t want to find the answer using expanding, there is also another method of expanding.
(a+b)^2 = a^2 - b^2
in this case, 16x^2 will be a^2 and 25 will be b^2. not sure whether you’ve learn this but yea.
Answer:
110 IQ too!
Step-by-step explanation:
For statistical problems, especially for ones with large enough sample sizes like this one (n = sample size = 100), the means for various samples is usually equal to the population mean.
It is the standard deviation of sample that differs from the standard deviation of the population through
σₓ = σ/√n
But, The mean of the sample = The population mean
μₓ = μ = 110 IQ
(6,3)
i think this is correct
So make an angle measuring 45 degrees and name it DOG. Its doesn't matter where you start labeling as long as O is the midpoint. :)
