First, find the width by using the equation 2450 = 2x * x. Multiply the like terms, which results in 2450 = 2x^2. Now, divide both sides by 2, which is 1225 = x^2. The square root of 1225 is 35. Now, to find the perimeter, the equation should be P = 2(70+35). 40 + 35 = 105, and 105*2 = 210. Therefore, the perimeter is A. 210 m
Number 2 is asking what number added by x would result in a perfect square. The first numbers in each of the options for the question so see which one creates a perfect square after it is added to 1500.
√ 1500 + 56 = 2 √ 389
√ 1500 + 21 = 39
√ 1500 + 38 = √ 1538
√ 1500 + 39 = 9 √ 19
B. 21, 39 would be the correct answer because it is the only perfect square.
Initial amount is when no change has happened or when t=0 that iniital amoun tis 1 the growth factor welll, it grows by 40% each time of previous times
I would say growth factor of 1.4
f(x)=a(b)^t f(t)=1(1.4)^t initial amount is 1 grouth factor is 1.4
