Lindsey, Laurie, and Mike showed their work solving the equation -3.3 + 73 - 5 = 8. Identify the student with the invalid first step and (justify your reasoning)

Laurie - 3x + 7x - 5 = 8
-3x + 7x - 5 = 8

Lindsey -3x + 7x – 5 = 8
-3x + 7x = 13

mike -3x + 2x = 8
4x - 5 = 8

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
