Considering the formulas for the area and the perimeter of the rectangle, the one with the desired measures is given as follows:
a length of 3 units and a width of 4 units.
<h3>What are the area and the perimeter of a rectangle?</h3>
Considering a rectangle of length l and width w, we have that:
For a rectangle with a length of 3 units and a width of 4 units, we have that:
- A = 3 x 4 = 12 square units.
Hence it is the correct option.

solve for "r"
notice, the "r" value, goes in the equation as a decimal, so 5% is really 5/100 or 0.05 25% is 0.25 and so on
so... the "r" that you'll get, will be a decimal value, multiply that by 100, and you'll get the percentage notation of it
![\bf 6,000=2,500\left(1+\frac{r}{4}\right)^{4\cdot 10}\implies\cfrac{6000}{2500}=\left(1+\frac{r}{4}\right)^{40} \\ \quad \\ \cfrac{12}{5}=\left(1+\frac{r}{4}\right)^{40}\impliedby \textit{now, taking root }\sqrt[40]{\qquad } \\ \quad \\ \sqrt[40]{\cfrac{12}{5}}=\sqrt[40]{\left(1+\frac{r}{4}\right)^{40}}\implies \sqrt[40]{\cfrac{12}{5}}=1+\cfrac{r}{4} \\ \quad \\ \sqrt[40]{\cfrac{12}{5}}-1=\cfrac{r}{4}\implies 4\left( \sqrt[40]{\cfrac{12}{5}}-1 \right)=r \\ \quad \\ ](https://tex.z-dn.net/?f=%5Cbf%206%2C000%3D2%2C500%5Cleft%281%2B%5Cfrac%7Br%7D%7B4%7D%5Cright%29%5E%7B4%5Ccdot%2010%7D%5Cimplies%5Ccfrac%7B6000%7D%7B2500%7D%3D%5Cleft%281%2B%5Cfrac%7Br%7D%7B4%7D%5Cright%29%5E%7B40%7D%0A%5C%5C%20%5Cquad%20%5C%5C%0A%5Ccfrac%7B12%7D%7B5%7D%3D%5Cleft%281%2B%5Cfrac%7Br%7D%7B4%7D%5Cright%29%5E%7B40%7D%5Cimpliedby%20%5Ctextit%7Bnow%2C%20taking%20root%20%7D%5Csqrt%5B40%5D%7B%5Cqquad%20%7D%0A%5C%5C%20%5Cquad%20%5C%5C%0A%5Csqrt%5B40%5D%7B%5Ccfrac%7B12%7D%7B5%7D%7D%3D%5Csqrt%5B40%5D%7B%5Cleft%281%2B%5Cfrac%7Br%7D%7B4%7D%5Cright%29%5E%7B40%7D%7D%5Cimplies%20%5Csqrt%5B40%5D%7B%5Ccfrac%7B12%7D%7B5%7D%7D%3D1%2B%5Ccfrac%7Br%7D%7B4%7D%0A%5C%5C%20%5Cquad%20%5C%5C%0A%5Csqrt%5B40%5D%7B%5Ccfrac%7B12%7D%7B5%7D%7D-1%3D%5Ccfrac%7Br%7D%7B4%7D%5Cimplies%204%5Cleft%28%20%5Csqrt%5B40%5D%7B%5Ccfrac%7B12%7D%7B5%7D%7D-1%20%5Cright%29%3Dr%20%5C%5C%20%5Cquad%20%5C%5C%0A)
Answer:
3
Step-by-step explanation:
A difference of squares factors in general as
a² - b² = (a - b)(a + b)
Given the factor (- 5x + 3) of a difference of squares product.
Then the other factor is (- 5x + 3)
Answer:
A) I = $171.73
B) $4771.73
Step-by-step explanation:
We are told her loan is $4600 for 7 months.
Thus;
Principal; P = 4600
Time; T = 7 months = 7/12 year
Interest rate is given as 6.4%
Thus; r = 6.4
A) To get the interest, the Formula is;
I = PRT/100
I = (4600 × 6.4 × (7/12))/100
I = $171.73
B) Since interest is $171.73, it means amount she owes after the 7 months = $4600 + $171.73 = $4771.73
