Hello!

To factor you find the biggest number they can be divided by

The biggest number that all the number can be divided by is 10

Put the two together

10(3 + x + 4y)

Hope this helps!

A small cube has the volume shown. Its side length is 1.5 in less than a second larger cube. What is
eduard

The volume of the larger cube is 227 inches cube.

<h3 /><h3 /><h3>Volume of a cube is describe below:</h3>
  • v = L³

where

L = length

The small cube has the following volume:

  • v = 95 in³

Let

The side length of the small cube = x

Therefore,

95 = x³

x = ∛95

x = 4.56290264

x ≈ 4.6

Its side length is 1.5 inches less than a second larger cube. Therefore,

  • length of larger length cube = (x + 1.5 )inches = 4.6 + 1.5 = 6.1 inches

Therefore, the volume of the larger cube can be found as follows:

Volume = 6.1³

volume = 226.981

volume ≈ 227 inches³

Given the following triangle, if c = sqrt 5 and a = 2, find the measure of B to the nearest degree.
matrenka [14]
The measure of B will be given by:
cos θ= adjacent/hypotenuse
θ=B
adjacent=a=2
hypotenuse=c=√5
thus;
cos B=2/√5
thus
B=arccos 2/√5
B=26.565°~26°
