Answer:

area = 147 sq. cm

Step-by-step explanation:

area of rectangle: length times width; since we already have the width (10), we just have to find the length. length= 6+6; 12 equation: 10 x 12 = 120

area of top triangle: 1/2 base times height; base (6), height (5)

0.5(6) x 5; equation: 3 x 5 = 15

area of bottom triangle: 1/2 base times height; base (6), height (4)

0.5(6) x 4; equation 3 x 4 = 12

120 + 15 + 12 = 147

What is the simplified form of the following expression? (5 points)

jek_recluse [69]

$\huge \boxed{\mathbb{QUESTION} \downarrow}$

Simplify ⇨ (n⁵)(n²)

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

$\tt \: ( n ^ { 5 } ) ( n ^ { 2 } )$

To multiply powers of the same base, add their exponents.

$\tt \: n ^{5 + 2} \\$

Add 5 and 2 to get 7.

$= \boxed {\boxed{\bf \: {n}^{7} }}$

The first option n⁷ is the correct answer.

Find two positive numbers whose product is 25 and whose sum is a minimum. (if both values are the same number, enter it into bot

pshichka [43]

Let xy = 25, x and y > 0.

$y = \frac{25}{x}$
$\text{Denote S as: } x + y$
$S(x) = x + \frac{25}{x}$

$\text{Minimum: }S'(x) = 0, S''(x) > 0$
$S'(x) = 1 - \frac{25}{x^{2}}$
$1 - \frac{25}{x^{2}} = 0$
$x^{2} = 25$
$x = 5 (x > 0)$

$S''(x) = \frac{50}{x^{3}} > 0, (x > 0)$

Thus, at x = 5, there lies a minimum summation, and this forms a square with side length of 5.
