Find the area of the figure.

jonny [76]

Answer:

60 square feet

Step-by-step explanation:

Area of figure = area of rectangle + area of triangle

Rectangle:

Length = 10 ft

Width = 4 ft

Area = length * width

= 10 * 4

= 40 ft²

Triangle:

Base b = 12 - 4 = 8 ft

Height h = 10 - 5 = 5 ft

$Area=\frac{bh}{2}\\\\=\frac{8*5}{2}\\\\=4*5$

= 20 ft²

Area of the figure = 40 + 20 = 60 square feet

Simplify\left(2-\sqrt{3}\right)^2

Kobotan [32]

$\implies {\blue {\boxed {\boxed {\purple {\sf { C) \:7 + 4 \sqrt{3}}}}}}}$

$\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\red{:}}}}}$

${( - 2 - \sqrt{3} )}^{2}$

$= ({ - 2})^{2} - 2.( - 2). \sqrt{3} + { (\sqrt{3}) }^{2}$

$= 4 + 4 \sqrt{3} + 3$

$= 7 + 4 \sqrt{3}$

$({a - b})^{2} = {a}^{2} - 2ab + {b}^{2}$

$\sqrt{a} \times \sqrt{a} = a$

If the numbers 1, 2, 4, 8, 16, 32, 64, 128 and 256 are arranged in a 3x3 array (table) so that he product of the numbers in any

musickatia [10]

I did it by recognizing that they were all powers of two and that exponents add...so we are looking for a standard magic square for the number 0 thru 8, since 1, 2, ..., 256 are the numbers 2^0 thru 2^8...
The numbers are

128, 4, 8
1, 16, 256
32, 64, 2
Each row, column and diagonal's product is 2^12 or 4096.
Good problem
