Answer:

220

Step-by-step explanation:

The surface area is given by

SA = 2 ( lw+wh+lh) where l is length h is height and w is width

SA = 2(3*4 + 3*14+ 4*14)

= 2(12+42+56)

= 2(110)

= 220

<h3>What is the equation of a line passing through two given points in 2 dimensional plane?</h3>

Suppose the given points are (x_1, y_1) and (x_2, y_2), then the equation of the straight line joining both two points is given by

$(y - y_1) = \dfrac{y_2 - y_1}{x_2 - x_1} (x -x_1)$

The equation of the line is found as;

$\rm y-y_1= \frac{y_2-y_1}{x_2-x_1} \\\\ \rm y-9= \frac{31-9}{2+5} (x+5)\\\\ 7y-63 = \frac{31-9}{2+5} (c+5)\\\\ 7y-63=22x+110\\\\ 7y= 22x+173 \\\\ but ,x=13\\\\ 7y=22 \times 13 +173\\\\ y= \frac{1259}{7} \\\\ y= 179$

Write the area as a product:<br> 3x^2 - 7x - 6

bulgar [2K]

Answer:

product is a ⋅ c = 3 ⋅ − 6 = − 18 and whose sum is b = − 7 .

Step-by-step explanation:

Factor

− 7 out of − 7 x .

3 x 2 − 7 ( x ) − 6

Rewrite

−7 as 2 plus −9

3 x 2 + (2−9) x −6

Apply the distributive property.

3 x 2 + 2 x − 9 x − 6
