The answer would be 126 square inches because you have to break up the figures and figure out the area for each one so for the rectangle the area would be 75 because of the formula length times width then for the square it would be 16 because the formula is the side (squared) then for the last one the parallelogram it would be 35 because of the formula base times height. Hope this helped :)

The volume of a rectangular prism is (x^3 – 3x^2 + 5x – 3), and the area of its base is (x^2 – 2). If the volume of a rectangula

bixtya [17]

Answer:

The height of the prism is equal to $h=(x^{3}-3x^{2}+5x-3)/(x^{2}-2)$

Step-by-step explanation:

we know that

The volume of a rectangular prism is equal to

$V=Bh$

where

B is the area of the base of the prism

h is the height of the prism

In this problem we have

$V=x^{3}-3x^{2}+5x-3$

$B=x^{2}-2$

substitute in the formula and solve for h

$x^{3}-3x^{2}+5x-3=(x^{2}-2)h$

$h=(x^{3}-3x^{2}+5x-3)/(x^{2}-2)$

Answer:

20 m

Step-by-step explanation:

Here, we will take,

The distance from top of the building to the tip of the shadow = Hypotenuse = 37 m

The length of shadow of the building = base = 32 m

let, height of the building = perpendicular = p

According to the Pythagoras Theorem,

(Hypotenuse)² = (Base)² + (Perpendicular)²

h² = b² + p²

p² = h² - b²

p² = 37² - 32²

p² = 1369 - 1024

p² = 345

p = 18.57

and if we round the solution to nearest tenth it will be 20.

Hence, height of the building is 20 m.

(A) x^2 + 6x + 9 = 0 (B) 8x^2+ 5x - 6 = 0 (C) (x + 4)^2 - 36 = 0

inna [77]

Answer:

Query (A)

${ \rm{ {x}^{2} + 6x + 9 = 0 }} \\ { \rm{(x + 3)(x - 1) = 0}} \\ { \boxed{ \rm{x = {}^{ - }3 \: \: and \: \: 1 }}}$

Query (B)

${ \rm{ {8x}^{2} + 5x - 6 = 0}} \\ \\ { \rm{x = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac } }{2a} }} \\ \\ { \rm{x = \frac{ - 5 \pm \sqrt{217} }{16} }} \\ \\ { \boxed{ \rm{ \: x = 0.608 \: \: and \: \: {}^{ - } 1.233}}}$

Query (C)

${ \rm{ {(x + 4)}^{2} - 36 = 0 }} \\ \\ { \rm{ {(x + 4)}^{2} = 36 }} \\ \\ { \rm{x + 4 = \pm6}} \\ \\ { \boxed{ \rm{x = 2 \: \: and \: \: {}^{ - } 10}}}$

sweet [91]

Answer:

0.42 it is terminating because it goes 66666 but then changes to a 7 at the end

Step-by-step explanation:

5/12 is just like a division problem. You divide 5 by 12 to get 0.416666667 which is the full answer and you take the first two numbers after the decimal to be your answer. But if there is a 5 or higher after the second number you can round it to its nearest tenth.
