Michaela and Grace were trying to solve the equation: 4 x 2 − 100 = 0 4x 2 −100=04, x, squared, minus, 100, equals, 0 Michaela said, “I'll factor the left-hand side of the equation as ( 2 x + 10 ) ( 2 x − 10 ) (2x+10)(2x−10)left parenthesis, 2, x, plus, 10, right parenthesis, left parenthesis, 2, x, minus, 10, right parenthesis and solve using the zero product property.” Grace said, “I'll isolate the x 2 x 2 x, squared term by adding 100 100100 and dividing by 4 44 on both sides of the equation. Then I'll solve by taking the square root.” Whose solution strategy would work?

Both.

Step-by-step explanation:

Took the stupid quiz

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

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
