Ala make 19 cookies in 30 min and Jane make 30 in 45 min so what is total cookies made by both in 1.5 he

See explanation

Step-by-step explanation:

The last part of your question isn't well written but let me rewrite based on what I think should be there.

Ala make 19 cookies in 30 min and Jane make 30 in 45 min so what is total cookies made by both in 1.5 hour?

Since Ala makes 19 cookies in 30 minutes. The number of cookies made in 1.5 hours will be:

= 19 × 1.5hours/30 minutes

= 19 × 90min/30min

= 19 × 3

= 57 cookies

Jane make 30 in 45 min. The number of cookies made in 1.5 hours will be:

= 30 × 1.5hours/45minutes

= 30 × 90minutes/45minutes

= 30 × 2

= 60 cookies

The total cookies made by both will then be:

= 57 + 60

= 117 cookies

Note that 1.5 hours = 1.5 × 60 minutes = 90 minutes

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
