Find the surface area.

Triss [41]

Answer:

196 $ft^{2}$

Step-by-step explanation:

Surface are of 2 rectangles = 2(2*4) = 16 $ft^{2}$

surface are of the base rectangle = 4*3 = 12 $ft^{2}$

Area of tow triangles =2( $\frac{1}{2}$ * 2* 2)= 4 $ft^{2}$

total = 16+12+4

= 196 $ft^{2}$

If m angle RTS = 8x + 18, find x so that line TR is perpendicular to line TS

Kitty [74]

Answer:

Point T is the right angle of the triangle, so RTS = 90 degrees

8x + 18 = 90 (degrees)

8x = 72

Which functions have an additive rate of change of 3? Select TWO options

Pachacha [2.7K]

Answer:

Second table.

Step-by-step explanation:

A function has an additive rate of change if there is a constant difference between any two consecutive input and output values.

The additive rate of change is determined using the slope formula,

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

From the first table we can observe a constant difference of -6 among the y-values and a constant difference of 2 among the x-values.

$m = \frac{ - 9- - 3}{4-2} = - 3$

For the second table there is a constant difference of 3 among the y-values and a constant difference of 1 among the x-values.

The additive rate of change of this table is

$m = \frac{ - 1 - - 4}{3 - 1} = 3$

Therefore the second table has an additive rate of change of 3.
