Answer:

81x² + 90x + 48y + 64

Step-by-step explanation:

(9x+8)² = (9x+8)(9x+8) = 9x*9x + 9x*8 + 8*9x + 8*8 = 81x² + 72x + 72x + 64

= 81x² + 144x + 64

then:

(9x+8)² -54x+48y = (81x² + 144x + 64) -54x + 48y = 81x² + 90x + 48y + 64

What is the equation in point slope form of the line passing through (0,5) and (-2,11)

IRISSAK [1]

The equation of the line passing through $(x_1,y_1)$ and $(x_2,y_2)$ is

$\frac{x-x_1}{y-y_1} =\frac{x_2-x_1}{y_2-y_1}$ . Here

$\frac{y_2-y_1}{x_2-x_1}$ is the slope of the line.

Substituting numerical values, the equation of the line is

$\frac{x-0}{y-5} =\frac{-2-0}{11-5} \\ \frac{x}{y-5} =-\frac{1}{3} \\ 3x=5-y\\ 3x+y=5$

The equation of the line is $3x+y=5$

Elena needs to find a table that will fit three cube-shaped cases, each containing a frog.

iVinArrow [24]

The area of the table is 3.75 feet
The boxes are .83333 feet by .83333 feet so that area is .69
.69x3 is 2.07 so yes they will fit on top of the table

The LATERAL Surface Area for the shape below is ____________. (assume the bases are the larger faces on the top and bottom.)

Zolol [24]

Answer:

$LA=210\ cm^2$

Step-by-step explanation:

we know that

The lateral area of the figure is given by

$LA=Ph$

where

P is the perimeter of the base (larger faces)

h is the height

Find the perimeter of the base P

$P=2(11+10)=42\ cm$

we have

$h=5\ cm$

substitute in the formula of lateral area

$LA=42(5)=210\ cm^2$
