Can I get some help with this? Thanks​
iris [78.8K]

Step-by-step explanation:

first you need to know that angle 4 and angle d are the same measurement. so then you have to notice that a straight line is equal to 180 degrees. by knowing this you can make this equation

x+30+ 2x +15= 180

next combine like terms:

3x+ 45=180

next subtract 45 from both sides

3x=135

next divide by 3 on both sides to get x alone. this will give you your answer.

x=45

once you know this plug 45 into you equation to do d the value of the angle 4

The formula for volume of this rectangular prism is: v=2x^3+17x^2+46x+40 find an expression for the missing side length. Show al
vodka [1.7K]

Answer:

the missing side length is (2x+5)

Step-by-step explanation:

we know that the volume of the rectangular prism is equal to

v=LWH

In this problem we have

v=L(x+4)(x+2)

v=2x^3+17x^2+46x+40

using a graphing tool find the x-intercepts of the function

see the attached figure

The x-intercepts are

x=-4, x=-2.5, x=-2

so

v=2(x+2.5)(x+4)(x+2)

v=(2x+5)(x+4)(x+2)

therefore

the missing side length is (2x+5)
