When you write it as an inequality you get x + 19 ≈ 8.2 and when you solve it it should look like x + 19 ≈ 8.2
19 ≈ - <u>19
</u> x ≈ -10.8<u>

What is the gcf of 378,132

Semmy [17]

First, find the prime factorization of both numbers.

378/2 = 189
189/3 = 63
63/3 = 21
21/3 = 7
7/7 1

378 = 2 * 3^3 * 7

132/2 = 66
66/2 = 33
33/3 = 11
11/11 = 1

132 = 2^2 * 3 * 11

For the GCF, choose the common factors with lower exponent.

378 = 2 * 3^3 * 7
132 = 2^2 * 3 * 11

From 2 and 2^2 choose 2.
From 3 and 3^2 choose 3.
7 and 11 are not common, so do not choose them.

GCF = 2 * 3 = 6

What is the surface area?

mash [69]

$\large\bf{\underline{Answer:}}$

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎ $\large\bf{ = 3000 \:ft^2}$

__________________________________________

$\large\bf{\underline{Given:}}$

A 3 dimensional figure with 5 sides
it has 3 rectangles with dimensions 28 ft and 25 ft
And 2 triangles with base =30 ft and height = 20 ft

$\large\bf{\underline{To\: find:}}$

Total surface area of figure

$\large\bf{\underline{Therefore:}}$

$\bf{area \:of\: figure}$

‎ㅤ ${\bf = area \:of \:3\: rectangles + 2 \: triangles}$

$\large\bf{\underline{Formulas:}}$

$\boxed{\bf\pink{area\:of\: triangle= \frac{1}{2}\times base\times height}}$

$\boxed{\bf\pink{area\:of\: rectangle=length\times breadth}}$

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎ $\large\bf{= 3\times (28 \times 25 )+ 2(\frac{1}{2} \times 30 \times 20)}$

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎ $\large\bf{= 3 \times 800 + 2 \times 300}$

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎ $\large\bf{=2400+ 600}$

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎ $\large\bf{= 3000}$
