Answer:

${5 x }^{2} +10x$

Step-by-step explanation:

$5x(x+2)$

$5x \times x+5x \times 2$

$5(x \times x)+5x \times 2$

$5 {x}^{2} +5x \times 2$

$5 {x}^{2} + 10x$

A block of stone measures 15 cm X 15 cm X 20 cm. What is the total surface area of the stone?(Hint: A block has six sides.)

BARSIC [14]

$Look\ at\ the\ picture.\\\\2\ sides:\ 15cm\times15cm\\\\Area:A_1=2\times(15cm\times15cm)=2\times225cm^2=450cm^2\\\\4\ sides:15cm\times20cm\\\\Area:A_2=4\times(15cm\times20cm)=4\times300cm^2=1200cm^2\\\\Area\ of\ the\ block:\\\\A=A_1+A_2\\\\\boxed{A=450cm^2+1200cm^2=1650cm^2}$

Use the given conditions to write an equation for the line in point-slope form. Passing through (2,-3) with x-intercept = -2

goldfiish [28.3K]

The equation for line is $y=-\frac{3}{4} x-\frac{3}{2}$

Explanation:

It is given that the line passes through the point $(2,-3)$ with x-intercept = -2

The x intercept is the value of x when y = 0.

Thus, it can be written in coordinate as $(-2,0)$

Now, we shall determine the slope using the points $(2,-3)$ and $(-2,0)$

$m=\frac{y_2-y_1}{x_2-x_1}$

Substituting, we get,

$m=\frac{0+3}{-2-2} \\m=-\frac{3}{4}$

Thus, the slope is $m=-\frac{3}{4}$

Now, we shall substitute the point $(2,-3)$ and slope $m=-\frac{3}{4}$ in the point-slope formula $y-y_1=m(x-x_1)$ , we get,

$y+3=-\frac{3}{4} (x-2)$

Multiplying both sides by 4, we get,

$4y+12=-3x+6$

Subtracting both sides by 12,

$4y=-3x-6$

Dividing both sides by 4, we get,

$y=-\frac{3}{4} x-\frac{3}{2}$

Thus, the equation of the line is $y=-\frac{3}{4} x-\frac{3}{2}$
