Answer:

a=5x^2+10x units^2

Step-by-step explanation:

The area of a rectangle is:

a=height*width

a=5x(x+2)

a=5x*x +5x*2

a=5x^2+10x units^2

If ΔABC is reflected across the y-axis, what are the resulting coordinates for points A', B', and C'
Sever21 [200]

Answer:

Step-by-step explanation:

Reflection across the y axis changes the x value.

Reflection across the x axis changes the y value.

This is counterintuitive, but it is correct.

A'

(-1,6)

B'

(-2,1)

C'

(-5,2)

Do you see what happened. All the values for x become - values because you are moving an equal distance in the -x direction

Colin and amil Each built boxes with a volume of 8 ft.³ Collins box is a cube almils box is a rectangular prism the length of am
SOVA2 [1]

Answer:

4' x 2' x 1'

Step-by-step explanation:

Collins' cube has a volume of that is the length of any side, x, cubed:  Vol = x^3.  Since his box has 8^3, we can say that x = 2.  <u>[2^3 = 8]</u>

Amil's box has one side that is 2x.  That side would be 2*2 = 4 feet.  His volume is also 8 ft^3.  Amil's box also has a volume of 8 ft^3.

His box dimensions are therefore:  (4)(X)(Y) = 8 ft^3 , where X and Y are whole-number dimensions for the other 2 dimensions of his box.

(4)(X)(Y) = 8 ft^3

      X*Y = 2

The only combination of whole numbers for which this this would work is 1 and 2.

Amil's box is 4' x 2' x 1' or 8 ft^3

Sanjay graphs a quadratic function that has x-intercepts of –3 and 7. Which functions could he have graphed?
kykrilka [37]

we will select each options and find zeros

(a)

g(x)=x^2-4x-21

for finding x-intercept , we can set g(x)=0

and then we can solve for x

g(x)=x^2-4x-21=0

now, we can factor it

(x-7)(x+3)=0

we get

x=7,x=-3

so, this is TRUE

(b)

g(x)=(x-3)(x+7)

we can set it to 0

and then we can solve for x

g(x)=(x-3)(x+7)=0

we get

x=3,x=-7

so, this is FALSE

(c)

g(x)=3x^2-12x-63

we can set it to 0

and then we can solve for x

g(x)=3x^2-12x-63 =0

3(x^2-4x-21) =0

3(x-7)(x+3) =0

x=-3,x=7

so, this is TRUE

(d)

g(x)=-(x+3)(x-7)

now, we can set it to 0

and then we can solve for x

g(x)=-(x+3)(x-7)=0

x=-3,x=7

so, this is TRUE

(e)

we have

g(x)=x^2+4x-21

now, we can set it to 0

and then we can solve for x

g(x)=x^2+4x-21=0

(x+7)(x-3)=0

x=-7,x=3

so, this is FALSE

Can someone check this one for me , thank you!
Rudik [331]

Answer:

C

Step-by-step explanation:

Using sum/difference to product identity

• sin x - sin y = 2 cos(\frac{x+y}{2}) sin (\frac{x-y}{2})

with x = 4Θ and y = 2Θ

Then

sin(4Θ) - sin(2Θ)

= 2 cos(\frac{4o+2o}{2}) sin(\frac{4o-2o}{2})

= 2cos(3Θ)sinΘ → C
