Answer:
A)
Step-by-step explanation:
length = x +x + 2 = 2x + 2
Width = 2+ x
Area of rectangle = length *width
(x +2)(2x + 2) = 110
Use FOIL method
x*2x + x*2 + 2*2x + 2*2 = 110
2x² + <u>2x + 4x</u> + <u>4 - 110</u> = 0 {Combine like terms}
2x² +6x - 106 = 0
a = 2 ; b = 6 ; c = -106
b² - 4ac = 6² - 4*2*(-106)
= 36 + 848
= 884
x = 5.93 m
24x-8y=56 is the same as y=3x-7
Answer:
<u><em>They bought the orange book </em></u>
Step-by-step explanation:
The easiest way to figure this problem out would be to break it down so it seems more simple.
6 students, 18 items, each paid $24.
8*18 = 144
144/6 = $24
You would just multiply the cost of the red book, blue book, and orange book by the 18 items. Then divide your answer by the number of students.
Your answer would be 1250 mL. hope that helped
Answer:
-10
Step-by-step explanation:
y = (x - 5) (x + 2)
y = (3 - 5) (3 + 2)
y= (-2) (5)
y= -2 x 5
y= -10
