Graph the function. F(x)=5/9(x+9)(x+3)

5x + 2 = 8x + 5 Help me before I die quick math is so hardddddd

Answer:

x = -1

Step-by-step explanation:

Note: when you send a number across it can change it sign. If it is positive it will turn negative.

5x + 2 = 8x + 5

Send 8x across

5x + 2 - 8x = 5

send 2 across

5x - 8x = 5 - 2

- 3x = 3

Divide both sides by - 3

- 3x/- 3 = 3/- 3

- 3 cancel out - 3

x = 3/ - 3

3 divided by - 3 is - 1

x = -1

The circular opening of an ice cream cone has a diameter of 7 centimeters. The height of the cone is 10 centimeters. What is the

marin [14]

We have been given that the circular opening of an ice cream cone has a diameter of 7 centimeters. The height of the cone is 10 centimeters. We are asked to find the volume of the ice-cream cone.

We will use volume of cone formula to solve our given problem.

$V=\frac{1}{3}\pi r^2 h$ , where

r = Radius of cone,

h = Height of cone.

We know that diameter is two times the radius, so radius will be half of diameter that is $r=\frac{7}{2}$ .

$V=\frac{1}{3}\pi\cdot (\frac{7}{2})^2\cdot 10$

$V=\frac{1}{3}\pi\cdot (\frac{49}{4})\cdot 10$

$V=128.2817$

$V\approx 128.3$

Therefore, the volume of the cone would be approximately 128.3 cubic cm.

Answer:

38

Step-by-step explanation:

So fill in the variables and solve from there:

(5)(4)+2(3)^2 = ?

20 + (2)(9) = ?

20 + 18 = ?

? = 38
