What is the area of a rectangle with side lengths 2/5 feet and 4/6 feet?

kotegsom [21]

Answer:

$\frac{4}{15}$ (4/15)

Step-by-step explanation:

$\frac{4}{6}=\frac{2}{3}$

$\frac{2}{5}*\frac{2}{3};$

1- Multiply the numerators:

$2*2=4$

2- Multiply the denominators:

$5*3=15$

3- Thus:

$\frac{2}{5}*\frac{2}{3}= \frac{4}{15}$

Hope this helps ;)

const2013 [10]

Using Pythagorean theorem

$\\ \sf\longmapsto H^2=P^2+B^2$

$\\ \sf\longmapsto H^2=5^3+3^2$

$\\ \sf\longmapsto H^2=25+9$

$\\ \sf\longmapsto H^2=34$

$\\ \sf\longmapsto H=\sqrt{34}$

$\\ \sf\longmapsto H=5.22$

Algebra I

Standard Form: ax² + bx + c = 0
Quadratic Formula: $\displaystyle x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}$

Step-by-step explanation:

Step 1: Define

Identify

5x² - 3x - 7 = 0

↓

a = 5, b = -3, c = -7

Step 2: Solve for x

Substitute in variables [Quadratic Formula]: $\displaystyle x=\frac{3 \pm \sqrt{(-3)^2-4(5)(-7)}}{2(5)}$
[√Radical] Evaluate exponents: $\displaystyle x=\frac{3 \pm \sqrt{9-4(5)(-7)}}{2(5)}$
[√Radical] Multiply: $\displaystyle x=\frac{3 \pm \sqrt{9+140}}{2(5)}$
[√Radical] Add: $\displaystyle x=\frac{3 \pm \sqrt{149}}{2(5)}$
[Fraction] Multiply: $\displaystyle x=\frac{3 \pm \sqrt{149}}{10}$
