Answer:

4x^2-21x-2

Step-by-step explanation:

Given that:

Difference of two trinomials is x^2 - 10x + 2

One of the two trinomials is  3x^2 - 11x - 4

To find:

The other trinomial = ?

Four options are:

2x2 - x - 2 \\2x2 + x + 6 \\4x2 + 21x + 6\\ 4x2 - 21x - 2

Solution:

Let the two trinomials be A and B.

Given A - B = x^2 - 10x + 2

B = 3x^2 - 11x - 4

We have to find the other trinomial A.

A - B = x^2 - 10x + 2

A - (3x^2 - 11x - 4) = x^2 - 10x + 2

\Rightarrow A = x^2 - 10x + 2 + (3x^2 - 11x - 4)

\Rightarrow A = 4x^2-21x-2

So, the correct answer is 4x^2-21x-2.

Goryan [66]

Answer:

The volume of the triangular prism is V=72\ cm^3

Step-by-step explanation:

we know that

The volume of the triangular prism is equal to

V=BL

where

B is the area of the triangular face

L is the length of the prism

step 1

Find the area of the triangular face

The area of a triangle is equal to

B=\frac{1}{2} bh

we have

b=3\ cm\\h=4\ cm

substitute

B=\frac{1}{2}(3)(4)=6\ cm^2

step 2

Find the volume

we have

B=6\ cm^2

L=12\ cm

substitute in the formula of volume

V=6(12)

V=72\ cm^3

The formula for the surface area of a sphere is 4πr^2

This can be used in the following way, getting the diameter at 18.3:
18.3/2 = 9.15
Saying PI is 3.14 you can do this:

SA = 4*3.14*9.15^2 = 1051.6 m^2

Formula for volume is:
(4/3)πr^3

V = (4/3)*3.14*9.15^3 = 3207.2 m^3

PLS HELP ASAP:Find all the missing elements:
adelina 88 [10]

Answer:

b ≈ 9.5, c ≈ 14.7

Step-by-step explanation:

Using the Sine rule in Δ ABC, that is

\frac{a}{sinA} = \frac{b}{sinB} , substitute values

\frac{7}{sin23} = \frac{b}{sin32} ( cross- multiply )

b × sin23° = 7 × sin32° ( divide both sides by sin23° )

b = \frac{7sin32}{sin23} ≈ 9.5 ( to the nearest tenth )

Also

\frac{a}{sinA} = \frac{c}{sinC}

\frac{7}{sin23} = \frac{c}{sin125} ( cross- multiply )

c × sin23° = 7 × sin125° ( divide both sides by sin23° )

c = \frac{7sin125}{sin23} ≈ 14.7 ( to the nearest tenth )
