I think that is going to be x-3
180 eggs. That’s because 6 x 6 = 36 so we know how many eggs are in each tray. Then there are 5 trays with 36 eggs so 5 x 36 = 180
Answer:
x² + 4x - 21
Step-by-step explanation:
Given the solutions of x = 3 and x = -7, moving the constant to the other side and setting both equations equal to '0':
x - 3 = 0 and x + 7 = 0
So, the two binomials that make up the quadratic are:
(x - 3)(x + 7)
Use FOIL: x² + 7x - 3x - 21
Combine like terms: x² + 4x - 21

Answer:
Area: 42 cm²
Perimeter: 28.4 cm
Step-by-step explanation:
Simply plug in 4.2 cm for x into x + 5.8 to find the width. You width should be 10.
Area: Multiply 10 by 4.2 and you should get 42
Perimeter: Add up all the sides together (4.2 x 2 + 10 x 2) and you should get 28.4
