Answer:

  1. 10
  2. 15ab

Step-by-step explanation:

1. The square of the binomial is ...

  (* -2m)^2 = *^2 -4m* +4m^2

Matching terms, you find ...

  *^2 = 100

  -4m* = -40

Both of these equations tell you the value of * is 10.

___

2. Same deal. Multiply ou the square and see what you have.

  (3a +2.5b)^2 = 9a^2 +15ab +6.25b^2

The term missing on the right side of the given equation is 15ab.

A number of robbers were discussing how best to share some stolen rolls of
kupik [55]

Answer:

83

Step-by-step explanation:

Let the number of robbers be x

If they share 6 rolls each, the tota rolls will be 6x and since they have five remainder, the overall total is then 6x+5

In case they share 7 rolls each, it means they have 7x rolls but here they will be less 8 rolls hence 7x-8 is the overall total.

Equating these two

7x-8=6x+5

Arranging similar terms

7x-6x=8+5

x=13

Therefore, the robbers are 13

The rolla they have will be

6(13)+5=83

Or

7(13)-8=83

The graph of which function does not have a y-intercept of (0, 1)?
Komok [63]

Answer:

For example, the function y=x^{2} does not have a y-intercept of (0, 1). To prove this, let's make x=0, and if the value of 'y' is different from 1, then, the graph does nt have a y-intercept of (0,1):

y=x^{2} ⇒ y=(0)^{2} ⇒ y=0

Therefore, the y-intercept is at (0, 0) not (0, 1).
