Help me or give me answer key plz asap

Answer:

x=10

Step-by-step explanation:

according to the question

(x+2)(x-2)=96

=>x^2-4=96

=>x^2=96+4

=>x^2=100

=>x=√100

Therefore

x=10

x=-10

As width and length can't be negative

So x=10

Width=10-2=8

Length=10+2=12

12×8=96 (proven)

Answer:

Please check the explanation.

Step-by-step explanation:

As we know that the area of a rectangle is defined by multiplying the length by the width.

Given

substituting all the given values in the formula to find the value of x.

[tex]A=l\times w[/tex]

[tex]96=\left(x+2\right)\times \left(x-2\right)[/tex]

[tex]96=x^2-4[/tex]

[tex]x^2-4=96[/tex]

subtract 96 from both sides

[tex]x^2-4-96=96-96[/tex]

[tex]x^2-100=0[/tex]

[tex]x^2=100[/tex]

[tex]\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}[/tex]

[tex]x=\sqrt{100},\:x=-\sqrt{100}[/tex]

[tex]x=10,\:x=-10[/tex]

Putting x = -10 in the length and width will make the length and width negative, which can not be possible.

i.e.

length = l = x+2 = -10+2 = -8 units

width = w = x-2 = -10-2 = -12 units

Therefore, x=-10 must be excluded.

Now, putting the length of x = 10.

i.e.

length = l = 10+2 = 10+2 = 12 units

width = w = x-2 = 10-2 = 8

[tex]A=l\times w[/tex]

96 = 12 × 8

96 = 96

Therefore, the correct value of x = 10

Answer:

174 squares

Step-by-step explanation:

I would start by finding the surface area of the rectangular prism. You can use 2(wl+hl+hw).

2(wl+hl+hw)

2(3*5+9*5+9*3)

2(15+45+27)

2(87)

174 cm^2

The area of squares 1 cm edges would be 1 because 1*1=1, so you could find how many of them would fit on the surface area by dividing 174 by 1, which equals 174.

Answer:

[tex]y=\frac{5}{2}x-13[/tex]

Step-by-step explanation:

Given the equation

[tex]y=-\frac{2}{5}x-1[/tex]

comparing the equation with the slope-intercept form[tex]y=mx+b[/tex]

Here,

so the slope of the line is m = -2/5

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line,

so  the slope of the perpendicular line will be: 5/2

Therefore, the point-slope form of the equation of the perpendicular line that goes through (2,-8) is:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-\left(-8\right)=\frac{5}{2}\left(x-2\right)[/tex]

[tex]y+8=\frac{5}{2}\left(x-2\right)[/tex]

subtract 8 from both sides

[tex]y+8-8=\frac{5}{2}\left(x-2\right)-8[/tex]

[tex]y=\frac{5}{2}x-13[/tex]

Answer:

the slope is 2

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

y = mx + b

m = slope

b = y-intercept

Step-by-step explanation:

p(x) = 250x

6000 = 250x

x = 24

Answer:

24 tickets

Step-by-step explanation:

p(x) = 250x

Substitute 6,000 for p(x)

6,000 = 250x

Divide each side of the equation by 250

24 = x

1. 133 1/3% of 36=48

2. 260% of 360=936

Step-by-step explanation:

1. 133 1/3% of 36

=(133 1/3)%  of 36

=(133/1+1/3)% of 36

=(400/3)% of 36

=(400/3 *100) *36

=(400/300*36)

=4/3*36

=4*12

=48  Ans

---------------------------------------------------------------------------------------

2. 260% of 360

Answer:

x= (-13)

Step-by-step explanation:

You need to get x alone so you have to divide by 3 and -39/3 equals -13

Answer:

x = -13

Step-by-step explanation:

Divide both numbers by 3

3÷3 cancels each other out, leaving x

-39÷3= -13

Answer:

vertex = (3, 1 )

Step-by-step explanation:

The equation of a parabola in vertex form is

f(x) = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

f(x) = (x - 3)² + 1 ← is in vertex form

with vertex (h, k ) = (3, 1 )

Answer:

1st answer choice- You do not have enough jars because 20 jars will only hold 35 cups of applesauce.

Step-by-step explanation:

So 1.75 cups of applesauce fits in a jar. You have 20 jars so you multiply the cups of applesauce that can fit in the jar by how many jars you have. It will look like this: 1.75x20=? Now you multiply them and you get 35 which is how many cups of applesauce 20 jars will hold. You will have 5 cups of applesauce left over that cannot be transformed into a jar.

If you can please make my answer the brainliest that would be much appreciated. Thanks!
