Area of a rectangle = Length * Width
Area = 60cm^2
Length = 4
Width = GH = ? = x
60 = 4*x
solve for x
60/4 = x
x = 15
GH is 15cm
Multiply all 4 an the answer is gonna be the area
Answer: 1+1 = 2 :)
Step-by-step explanation:
Answer:
x = 15
y = 2
Step-by-step explanation:
X-4y=7 | ×6 |
-6x-3y=12 | ×1 |
6x - 24y = 42
-6x - 3y = 12
___________+
27y = 54
y = 54/27
y = 2
x - 4y = 7
x - 4(2) = 7
x - 8 = 7
x = 7 + 8
x = 15
Well, there are two solutions.
Add both sides by 15.75 then from here, you can use quadratic formula.
So your answer should be x = -2.44949 or 2.44949.
