Answer:
-295
Step-by-step explanation:
10^2=100
8x3=24
100-24=76
76x4=304
5+4=9
9-304=-295
We will see that the percentage in which the price decreases is 90%, thus the age is 90 years.

How old is Andrés?
We know that the percentage in which the price decreases is equal to the age of Andrés.
We can write:
P = $4,000 = $40,000*(1 - k)
Where k is the percentage in decimal form.
Solving for k:
k = ($40,000 - $4,000)/$40,000 = 0.9
To obtain the percentage, we multiply by 100%.
0.9*100% = 90%
We conclude that Andrés is 90 years old.

Option A is the answer of this question.
Answer:
Fourth - Degree trinomial
Step-by-step explanation:
It is a polynomial because there is no negative exponent or fractional exponent
We have highest exponent 4. so it is not cubic. For cubic polynomial highest exponent should be 3
Given expression have highest exponent 4 so its fourth degree. We have three terms 6x^4 , -10x and 9. so we say its trinomial.
Hence we name it as Fourth - Degree trinomial
We have 3 terms so this is not a monomial
Answer:
Length is 6.5in
Step-by-step explanation:
since
area of rectangle =length of rectangle into width of rectangle
Let A= area of rectangle
L = length of rectangle
W = width of rectangle
so
A=L*W
given A = 91in squared and W = 14in
so
L = A/W
L= 91/14 = 6.5
So the length of rectangle is 6.5in
