No, Amits reasoning is not correct. The problem used to represent the equation, (-5.75) × 7, was solved incorrectly. (-5.75) × 7 = (-40.25). We know this because a negative number times a positive number is always a negative number. So the correct answer for the change in Amits bank account is -40.25

a- Ivan's expression: $4.25 + $1.25(m)

Vicky's expression: $5.75 + $0.75(m)

b- $4.25 + $1.25(m) + $5.75 + $0.75(m)

[add $4.25 + $5.75]

$10.00 + $1.25(m) + $0.75(m)

[add $1.25(m) + $0.75(m)]

$10.00 + $2.00(m)

c- $10.00 + $2.00(m)

d- $10.00 + $2.00(m)

[2 ÷ 2 = 1]

[10 ÷ 2 = 5]

e- 2(m + 5)

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

this is not the answer this is just a question. is this middle school math?
