Celina says that each of the following expressions is actually a binomial in disguise:(Expressions in picture) For example, she

Juliette [100K]

Yes , she is right. All the remaining can be expressed in binomial.

II) $5x^3 * 2x^2 - 10x^4 + 3x^5 + 3x * (-2)x^4$

$10x^5 - 10x^4 + 3x^5 + -6x^5= 7x^5 - 10x^4$ is a binomial

iii) $(t+2)^2 - 4t = t^2 + 4t + 4 -4t = t^2 + 4$ is a binomial

iv) $5(a-1) - 10(a-1) + 100 ( a-1) = 5a - 5 - 10a + 10 + 100a -100 = 95a -95$ is a binomial

v) $( 2\pi r -\pi r^2)r - ( 2\pi r -\pi r^2)2r = 2\pi r^2 -\pi r^3 - 4\pi r^2 + 2\pi r^3$ = $-2\pi r^2 + \pi r^3$ is also a binomial

Help please ! Please

gizmo_the_mogwai [7]

Answer:

15, 8, 25 The teacher payed 0.40 per book.

Step-by-step explanation:

4/10 = 2/5 Simplify the 4/10 to find the unit rate.

15: 2/5 = 6/x Set up your proportion.

2x =30 Cross multiply

/2 /2 Divide both sides by 2 to isolate x

x =15

8: 2/5 = x/20 Set up proportion

40 =5x Cross multiply

/5 /5 Divide both sides by 5 to isolate x

8 =x

25: 2/5 = 10/x Set up proportion

2x =50 Cross multiply

/2 /2 Divide both sides by 2 to isolate x

x =25

Graph: y=mx+b To graph, you will need to use y=mx+b format

y= 2/5 x+2 2/5 is your unit rate. Your rate changes every 2 books bought. To graph, start at (0,2) and go up 2 and to the right 5, plot. Continue moving up 2 and to the right 5 to graph.

The teacher payed 0.40 per book because 2/5 simplifies to 0.40.
