Expression equivalent to a^2-144b^2

Answers

Answer:

(a - 12b)(a + 12b).

Step-by-step explanation:

a^2 - 144b^2

This is the difference  of 2 squares identity:

a^2 - b^2 = (a - b)(a + b)

So for the given expression we have:

(a - 12b)(a + 12b).

-  (as a is square root of a^2 and 12b is the square root of 144b^2.).

Given line 1, with coordinates (-7,-3) and (4,7), and line
2 with coordinates (7,-7) and (-3, 4), find the slope of line 2

Answers

Answer:

-11/10 (fraction) or -1.1 (decimal)

Step-by-step explanation:

The slope formula is m=(y2-y1)/(x2-x1)

x1 = 7

x2 = -3

y1 = -7

y2 = 4

So, it’s: (4 - (-7))/(-3-7)

= (4+7)/(-3-7)

= (11)/(-10)

= -11/10 or -1.1

I need help bad it’s like son 2 way table stuff

The first one I'll do is Physics because you know the amount of girls and total amount of students. Use the equation x+19=33. Note that x is the amount of boys we are trying to find. All you need to do is simply subtract 19 from both sides to get x alone.

                                             x + 19 = 33

                                                  -19   -19

                                             x         = 14

For the total that's going up and down, you can do this same process again, but just using x for girls instead of boys. Your equation should look like 47+x=80. Once again, subtract 47 from both sides.

                                             47 + x = 80

                                             -47        -47

                                             x         =  33

Now you can find whole row for boys. This equation will be a little longer, but it's still pretty easy. 18+x+14=47 is what we will be using. We first will need to combine like terms (the 18 and 14), then subtract it off from both sides to get x alone.

                                             18 + x + 14 = 47

                                                    x + 32 = 47

                                                        -32   -32

                                                     x         = 15

Moving onto the biology column, we'll be using the equation 15+x=21

                                             15 + x = 21

                                            -15        -15

                                             x         = 6

Now we can find out the girls column with this equation: x+6+19=33

                                           x + 6 + 19 = 33

                                           x + 25      = 33      

                                               -25         -25

                                                     x      = 8

Lastly, we can find the chemistry column by just adding 18+8 to get 26.

I know this was a little hard to follow along, so here's a picture of it finished:

Answer:

Prism A: 264; Prism B: 265.125

Step-by-step explanation:

✔️Surface area of the triangular prism = base area + Perimeter*Height of prism

Base area = ½*bh

b = 6 cm

h = 8 cm

Base area = ½*6*8 = 24 cm²

Perimeter of base = 6 + 8 + 10 = 24 cm

Height of prism = 10 cm

Surface area of the triangular prism = 24 + 24*10 = 264 cm²

✔️Surface area of rectangular prism = 2(LW + LH + HW)

L = 5.25 cm

W = 5.25 cm

H = 10 cm

Surface area of rectangular prism = 2(5.25*5.25 + 5.25*10 + 10*5.25)

= 265.125
