Your answer should be a polynomial in standard form. (7h^3+8h) -(9h^3+h^2-2h)=(7h 3 +8h)−(9h 3 +h 2 −2h)

Need answer this urgent and fast

Karo-lina-s [1.5K]

Answer:

56

Step-by-step explanation:

Hey There!

so this is a parallelogram so opposite angles are congruent

So basically what i am saying is that angle P is congruent to angle R

So we need to solve for x

We know that angle P and angle Q are supplements meaning that they will add up to 180

so we setup the equation

$180=3x+5+8x-12\\$

step 1 combine like terms

$3x+8x=11x\\5-12=-7$

now we have

180=11x-7

step 2 add 7 to each side

180+7=187

-7+7 cancels out

now we have

187=11x

step 2 divide each side by 11

187/11=17

x=17

now we plug in 17 to (3x+5) to get the value of angle R

17x3=51

51+5=56

therefore m∠R = 56

Are these(4,1) 1,-3) (2,0) solutions to this graph?

kogti [31]

(4,1) : no because the line is solid.
(1,-3) : yes because the line is not solid.
(2,0) : no because the line is solid.

Solid lines represent < or >, and if a point is on the line directly, it’s not included in the solution set.

What is the shape of the cross-section formed when a plane containing line AC and line EH intersects this cube? What is the area

liq [111]

Answer:

Area of given figure = 96 unit²

Step-by-step explanation:

Given:

Length of shape = 4 unit

Width of shape = 4 unit

Height of shape = 4 unit

Find:

Area of given figure

Computation:

All side of figure all equal

So,

Given figure is a cube

Number of faces of cube = 6

Area of base = side x side

Area of base = 4 x 4

Area of base = 16 unit²

Area of given figure = Area of base x Number of faces of cube

Area of given figure = 16 x 6

Area of given figure = 96 unit²

Answer:

y=3x

idk

Step-by-step explanation:

I know this is only half an answer, but for a they have the same slope and it's proportional so it has no b value.
