Answer:

c = −4x2−12x+7 /0

Step-by-stepexplanation:

Step 1: Add -c to both sides.

x^2 + 3x + c = 7/4 + c

-c -c

x2 + 3x = 7/4

Step 2: Add -x^2 to both sides.

x2 + 3x= 7/4

−x2 −x2

3x = 7/4 -2x

Step 3: Add -3x to both sides.

3x+ = 7/4−x2

-3x −3x

0 = -x2 -3x +7/4

Step 4: Divide both sides by 0.

0 = -x2 -3x +7/4

/0 /0

c = −4x2−12x+7

Answer:

c = −4x2−12x+7

Pls help many thanks

So, let's make these two values improper fractions so they're easier to work with. $4+\frac{1}{3}=\frac{12}{3}+\frac{1}{3}=\frac{13}{3} 3+\frac{1}{2}=\frac{6}{2}+\frac{1}{2}=\frac{7}{2}$

So, to get the rate he grew in those months we have:

$\frac{\frac{13}{3} \text{inches}}{\frac{7}{2}\text{months}} =\frac{26\text{inches}}{21\text{months}}$

And to get the rate he grew in one month we have to divide both our numerator and our denominator by 21 to get:

$\frac{\frac{26}{21} \text{inches}}{\text{month}}\approx \frac{1.24\text{inches}}{\text{month}}$ aka he grew 1.24 inches in a month.
