Answer:

86.9 cm^3

Step-by-step explanation:

You have to find the area of every face. Since the opposite sides have the same area, you can find three areas and then multiply by 2.

2(5.3x2)=21.2

2(4.5x2)=18

2(4.5x5.3)=47.7

You then add the values together...

21.2+18+47.7=86.9

Because there are four faces that have the measurement of 5.3*4.5, you do 4(5.3*4.5)

Because there are two faces have the measurement of 4.5*2, you do 2(4.5*2)

Which gives you an expression of 2(4.5*2)+4*(5.3*4.5)

Which is 113.4

PLS HELP f(x)=x^3−2x^2+12x−6 g(x)=4x^2−6x+4 What is (f−g)(x)?

vodomira [7]

Answer:

$(f - g)(x) = {x}^{3} - 6 {x}^{2} + 18x - 10$

Step-by-step explanation:

The given functions are:

$f(x) = {x}^{3} - 2 {x}^{2} + 12x - 6$

and

$g(x) = 4 {x}^{2} - 6x + 4$

We want to find

$(f - g)(x)$

Recall that:

$(f - g)(x) = f(x) - g(x)$

This implies that:

$(f - g)(x) = {x}^{3} - 2 {x}^{2} + 12x - 6 - (4 {x}^{2} - 6x + 4)$

$(f - g)(x) = {x}^{3} - 2 {x}^{2} + 12x - 6 - 4 {x}^{2} + 6x - 4$

We combine similar terms to get:

$(f - g)(x) = {x}^{3} - 6 {x}^{2} + 18x - 10$

Oak Street and Elm Street run parallel to each other. When Main Street

kozerog [31]

Answer:

110°

Step-by-step explanation:

The consecutive interior angles theorem states that when two parallel lines are cut by a transversal, the pair of angles formed which lie inside the parallel lines on the same side of the transversal are known as consecutive interior angles. This consecutive interior angles are supplementary (that is add up to 180°).

Therefore:

∠4 and ∠6 are consecutive interior angles. Hence:

∠4 + ∠6 = 180° (sum of co-interior angles)

∠4 + 70 = 180

∠4 = 180 - 70

∠4 = 110°
