A) 169p⁴qr÷ (-13pq³r)<br> b) 3(x +2y) +5x - (y + 7)<br> c (3x –4)( 5x- 1)
Veseljchak [2.6K]

Answer:

A)  -13p^33q^-2   or -13p^3/q^2

B)  8x + 5y - 7

C)  15x^2 -23x + 4

Step-by-step explanation:

A) 169/(-13) = -13     p^4/p = p^3    q/q^3  = 1/q^2  which can be written as q^-2 and r/r is 1. So if you put this all together you get  -13p^33q^-2   or -13p^3/q^2

B)  3(x +2y) + 5x - (y + 7)

     3x + 6y + 5x - y - 7   distributive property

     3x + 5x + 6y - y  -7   combine like terms

      8x + 5y - 7              Answer

C)  (3x-4) (5x - 1)    Foil multiply the first terms in each parenthesis. the outer terms, the inner terms and the last terms

(3x)(5x) + (3x)(-1) + (-4)(5x)  + (-4)(-1)

15x^2  -3x - 20x + 4  

15x^2 -23x + 4

Why are (4, 6) and (6, 4) not at the same point on a grid?
sdas [7]

Answer and Step-by-step explanation:

Notice that both these points are in the form of (x, y). "x" indicates that on the left-right axis (x axis), the point is x units away from the origin (0, 0). "y" indicates that on the up-down axis (y axis), the point is y units away from the origin.

In (4, 6), x = 4 and y = 6. This means that the point (4, 6) is 4 units to the right of the origin and 6 units up (see red dot on attachment).

In (6, 4), x = 6 and y = 4. This means that the point (6, 4) is 6 units to the right of the origin and 4 units up (see blue dot on attachment).

As can be seen, these two points do NOT coincide, so they are different.

A cylinder with a radius of 6cm and height of 15 cm has a cylindrical cut out of the
suter [353]

Answer:

V = 518cm^3

Step-by-step explanation:

Given

h = 15cm

R = 6cm

r =5cm

Required

The volume of the remaining cylinder

Before the cut-out, the cylinder has a volume (V) of:

V = \pi R^2h

After the cut-out, the cylinder has a volume of:

V = \pi [R^2 -r^2]h

So, we have:

V = 3.14* [6^2 -5^2]*15

V = 3.14* [36 -25]*15

V = 3.14* 11*15

V = 518cm^3
