Answer:
s = r1 s = 3.1 s = 3.1
or
v =a/s
v = 208/3.1
v = 67.0968
Step-by-step explanation:
I'm pretty sure that it is 3.5 or even 45
We divide the pennies 100 to convert pennies to dollar
1 pennies= 1/100 dollar
Then we will convert 6.02×10∧23 p to dollar
=1 dollar/100 pennie ×6.02×10∧23
= 6.02×10∧21
The total men and women and children in 250 m
=25×108
6.02×10∧21/2.5×10∧8
= 2.408×10∧13
The quadratic equation use to determine the thickness of the frame, x is 4x² + 10x - 1 = 0.
The correct option is D.
<h3>What is a quadratic equation ?</h3>
A quadratic equation is an algebraic equation of the second degree in x.. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term.
<h3>
According to the given information:</h3>
Total area = 7 square feet
and,
Total area = Length x Width
So,
7 = (2x + 3)(2x + 2)
7 = 4x2 + 4x + 6x + 6
7 = 4x2 + 10x + 6
4x2 + 10x + 6 - 7 = 0
4x2 + 10x - 1 = 0
Hence,
The quadratic equation use to determine the thickness of the frame, x is 4x² + 10x - 1 = 0.

I understand that the question you are looking for is:
Mary wants to hang a mirror in her room. the mirror and frame must have an area of 7 square feet. The mirror is 2 feet wide and 3 feet long. Square with an inner frame with height of 2 ft on the left frame and width of 3 ft on the top. Arrow on the bottom frame with an x and an arrow on the right frame with an x. Which quadratic equation can be used to determine the thickness of the frame, x?
A. x² + 14x - 2 = 0
B. 2x² + 10x - 7 = 0
C. 3x² + 12x - 7 = 0
D. 4x² + 10x - 1 = 0
The answer is 6.7 bc .09 times 74 equals 6.66 so you round the 6 to a 7.
