2 (9x-1) + 7 (x+6) = -60 (show work and solve for x)

2 answers:

7 0

So you start by distributing the 2 and 7 so you get (18x-2) +(7x+42) =-60

Then you add like terms giving you (25x+40)=-60

Then subtract 40 and you get 25x=-100

Finally you divide and get x=-4

A cone has a diameter of 6 cm and a height that is 3 times the diameter. Using 3.14 for pi, which of the following can be used t

Zinaida [17]

Option A: 1/3(3.14)(3cm)^2(18cm) is the correct answer

Step-by-step explanation:

Given

Diameter of Cone = d = 6 cm

Radius will be:

r = d/2 = 6/2 = 3 cm

Height of cone = h = 3d = 18 cm

The volume of cone is given by:

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

Putting the values

$V = \frac{1}{3} (3.14)(3)^2(18)$

Hence,

Option A: 1/3(3.14)(3cm)^2(18cm) is the correct answer

Answer both question for 20 points and brainliest

Dmitrij [34]

Answer:

1 - c

2 - A

Step-by-step explanation:

Hey There!

So for the first one we are given the dimensions of a rectangular prism and they want us to find the volume

Remember to find the volume we use the equation

V = length x width x height

so we just plug in the values

v = 2.6 x 2.1 x 3.9 = 21.294

the closest is 20 so C is your answer

For the second one we are given a triangular prism

and they want us to find the volume

$V=\frac{1}{2} bhl$

b = base (10.3)

l = length (4)

h = height (7)

7x4=28

28x10.3=288.4

then we divide by 2

288.4/2=144.2

so your selected answer is correct
