Step-by-step explanation:

I did the question on IXL, and got it right.

Answer:

(5y - 1)(5y + 1)

Step-by-step explanation:

Assuming you require the expression to be factorised.

25y² - 1 ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b) , then

25y² - 1

= (5y)² - 1²

= (5y - 1)(5y + 1)

Answer:

Below.

Step-by-step explanation:

25y²-1

This is the difference of 2 squares and it factors to (5y - 1)(5y + 1).

Answer:

Step-by-step explanation:

The simple answer is just move the left semi-circle to the right end and fill in the missing semi-circle.  So the answer just becomes the area of the full rectangle....

       area of the newly formed rectangle is 4 times 6  

       Area = 24

Answer:

C

Step-by-step explanation:

The diagonals of a rectangle are congruent, then

5x - 31 = 2x + 11 ( subtract 2x from both sides )

3x - 31 = 11 ( add 31 to both sides )

3x = 42 ( divide both sides by 3 )

x = 14

Then

RT = 2x + 11 = 2(14) + 11 = 28 + 11 = 39

The diagonals are each 39 units

Answer:

m=7

Step-by-step explanation:

Replace all occurrences of  +  −  with a single -. A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign because 1⋅ − 1 = − 1

7(m-13)=-42

Divide each term by  7  and simplify.

m-13=-6

Move all terms not containing  m  to the right side of the equation.

m=7

Answer:f(x)=-16(x-1)^2+22

Step-by-step explanation:

The equation for the trajectory of ball in the air is h(t) = -16t² + 32t + 6.

The differentiation of a function is defined as rate of change of its value at a point. It can be written as f'(x) =  lim h --> 0 (f(x + h) - f(x)) /(x + h - x).

It can also be said as the slope of the tangent for the  function at a given point.

Given that,

The maximum height reached by the ball  after 1 sec is 22 ft above ground.

And, the height at which it is thrown is 6 ft above the ground.

Which implies at 0 sec the height is 6 ft.

The quadratic function for the height can be written as,

h(t) = at² + bt + c

Substitute t = 0 to gat,

f(0) = a × 0² + b × 0 + c

=> c = 6

Now, for maximum height,

h'(t) = 0

=> 2at + b = 0

At maximum height t = 1

Then, the above expression becomes,

2a × 1 + b = 0

=> a = -b/2

Substitute t = 1 in h(t) = at² + bt + c to get,

22 = a + b + c

=> 22 = -b/2 + b + 6

=> b/2 = 16

=> b = 32

Then, a = -b/2

            = -32/2

            =-16

Thus substituting the corresponding values the equation can be written as h(t) = -16t² + 32t + 6.

Hence, the required equation for the path of the ball in the air is  h(t) = -16t² + 32t + 6.

Answer:

y=3    x= -5/2

Step-by-step explanation:

simultaneous equations

2x + 4y = 7  ------ eq 1

-2x + 3y = 14 --------eq2

(different signs add)

(eq 2 + eq 1)

-2x +(-2x) = 0

4y+3y = 7y

7+14 = 21

7y= 21

(divide both sides by 7)

y= 21/7= 3

2x + 4(3) = 7

2x+ 12=7

2x = 7-12

2x = -5

x= -5/2

Answer:

6/5

Step-by-step explanation:

If you are looking for the slope of the line it is 6/5 because starting from the origin you rise 6 (go up in this case) and run (go right in this case) 5 from the two points that you were given. The line is also going in an upwards direction so the slope is also positive. If you want to write the slope-intercept form equation you would use the slope intercept formula y=mx+b and plug in your slope (6/5) and your y-intercept, which is just 0 because it is at the origin and you would get y=6/5x or y=6/5x+0.

Answer:

g(h(x)) = 9x² + 12x - 3

h(g(x)) = -3x² - 19

Step-by-step explanation:

g(h(x)) = (3x² + 2)² - 7

= 9x² + 6x + 6x + 4 - 7

= 9x² + 12x - 3

h(g(x)) = 3(x² - 7) + 2

= 3x² - 21 + 2

= 3x² - 19

There will be 25 squares will it take to fill the large square. Option C is correct.

It is defined as a two-dimensional geometry that has four sides and four vertices. The sides of the square are equal in length. It is a regular quadrilateral.

The number of squares is obtained as the relation,

=n×n

As we obtained the value of n is 5.

The number of squares will it take to fill the large square is,

8x4=32

There are 32 ounces of stuffing in 4 of the pillow.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

A pillow contains 8 ounces of stuffing.

Now,

Since, A pillow contains 8 ounces of stuffing.

So, The amount of ounces in 4 of the pillow = 8 x 4

                                                                    = 32

Thus, There are 32 ounces of stuffing in 4 of the pillow.
