Answer:
D. A = x² + 44x = 808Step-by-step explanation:
Check if the relationship is linear. Verify the difference between areas.
We can see the difference is not common.
It means we can exclude options B and C.
The remaining options are quadratic (A and D).
Try the last column with option A:
4813 = 45² + 19084813 = 3933FalseVerify the last option:
4813 = 45² + 44*45 + 8084813 = 4813CorrectWe can check and confirm the other columns are correct as well.

for 4th
A=x²+44x+808
when
x=25
A=25²+44×25+808=2533{satisfied}
when x=30
A=30²+44×30+808=3028[satisfied]
when x=35
A=35²+44×35+808=3573[satisfied]
when
x=40
A=40²+44×40+808=4168{satisfied}

1. Cadence has a collection of 52 dolls that all have either blue-eyes or green-eyes.
Cadence has 16 more blue-eyed dolls than green-eyed dolls. How many green-eyed dolls
does Cadence have?
Answers
Answer:
Cadence has 18 more green eyed dolls
Step-by-step explanation:
1. 52-16=36
2. 36÷2=18
The number of dolls that have blue eyes and green eyes will be 34 and 18, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Rhythm has an assortment of 52 dolls that all have either blue-eyes or green-eyes. Rhythm has 16 additional blue-looked-at dolls than green-peered dolls.
Let 'x' be the number of blue-eyes dolls and 'y' be the number of green-eyes dolls. Then the equations are given as,
x + y = 52 ...1
x = y + 16 ...2
From equations 1 and 2, then we have
y + 16 + y = 52
2y = 52 - 16
y = 36 / 2
y = 18
The value of x is given as,
x = 18 + 16
x = 34
The number of dolls that have blue eyes and green eyes will be 34 and 18, respectively.

The size of a cell is typically found by capturing an image under a microscope then
using software to measure its diameter. Two cells are measured using this method:
Cell M: 7.65 x 10-3 centimeters
Cell N: 9.1 x 10-4 centimeters
What's the difference between the diameters of the two cells? Express your answer
using scientific notation.
Answers
Answer:
The difference is 6.74 * 10^-3 centimeters
Step-by-step explanation:
Firstly, we need to write the numbers as they would occur normally
we have this as;
7.65 * 10^-3 = 0.00765
9.1 * 10^-4 = 0.00091
So by subtracting, we have it that we subtract the value of the diameter of the cell N from that of the cell M since it is a bigger number
we have this as;
0.00765 - 0.00091 = 0.00674 and in scientific form is 6.74 * 10^-3 centimeters

In the end, the mean mileage for each block is taken and compared to that of the other blocks.
