Help please, kind of confused

Mathematics

Anvisha [2.4K]3 years ago

Answer:

Step-by-step explanation:

Yikes. This is quite a doozy, so pay attention. We will begin by factoring by grouping. Group the first 2 terms together into a set of parenthesis, and  likewise with the last 2 terms:

(2d^4+6d^3)-(18d^2-54d) and factor out what's common in each set of parenthesis:

2d^3(d+3)-18d(d+3). Now you can what's common is the (d + 3), so factor that out now:

(d+3)(2d^3-18d) BUT in that second set of parenthesis, we can still find things common in both terms, so we continue to factor that set of parenthesis, carrying with us the (d + 3):

(d+3)2d(d^2-9) BUT that second set of parenthesis is the difference of perfect squares, so we continue factoring, carrying with us all the other stuff we have already factored:

(d+3)2d(d+3)(d-3). That's completely factored, but it's not completely simplified. Notice we have 2 terms that are identical: (d + 3):

2d(d+3)^2(d-3) is the completely factored and simplified answer, choice 3)

Yes they are the same. The number on the right just has an extra zero. You can add an infinite amount of zeros to the end of a number without changing it's value.

PLEASE HELPP!! How do I solve 4(x-8) = -2(x-5). Picture above.
dimulka [17.4K]

Answer:

x=7

Step-by-step explanation:

4(x-8)= -2(x-5)

4x+32= -2x+10

+2x          +2x

6x-32=10

    +32    +32

6x= 42

divide by 6 on both sides

x=7

Two rectangular prisms have the same volume. The area of the base of the blue prism is 216 square units. The area of the base of
valina [46]

Answer:

D)The height of the red prism is three times the height of the blue prism

Step-by-step explanation:

Here is the complete question

Two rectangular prisms have the same volume. The area of the base of the blue prism is 2 1/6 square units. The area of the base of the red prism is one third that of the blue prism.

which statement is true?

a)The height of the red prism is one-third the height of the blue prism

B)The height of the red prism is the same as the height of the blue prism

C)The height of the red prism is six times the height of the blue prism.

D)The height of the red prism is three times the height of the blue prism

Solution

Since both prisms have the same volume, V = A₁h₁ = A₂h₂ where A₁ and A₂ are the areas of the red and blue prisms respectively and h₁ and h₂ are the heights of the red and blue prisms respectively. For the question, A₁ = A₂/3. Substituting this into the equation, A₁h₁ = A₂h₂

A₂h₁/3 = A₂h₂

h₁ = 3h₂ . So the height of the red prism is thee times the height of the blue prism.

Please help with the problem
worty [1.4K]

Answer:

95%

Step-by-step explanation:

0.6 of 40 is 24, she bought 24 green balloons.

24 × 1.5 = 36, she bought 36 yellow balloons.

So we have

40 red

24 green

36 yellow

Then from the rest of the information, 2 red, 2 green, and 1 yellow balloon all popped.

We now have

38 red

22 green

35 yellow

for a total of:

95 balloons out of 100 original balloons, 95%
