You use the discriminant (b²-sqr(4ac))/2a and if sqr(4ac) inferior to 0 then use i = sqr(-1)
Answer:
The required option are
Length = 4 and width = x+5
Length = 2 and width = 2x+10
Step-by-step explanation:
Area of the rectangle = Length × width
Given
Area = 4x+20
Factoring out the common terms
Area = 4x + 4(5)
Area = 4(x+5)
Length = 4 and width = x+5
This can also be written as
Area = 2(2x+10)
Length = 2 and width =2x+10
0.7037037037 is the 2(76)/6 to the third power
A) center is (0,0)
Radius = r^2 = 225 => r = 15
b)center is (0,0)
Radius r^2= 178
=> r =13.34
C) center is (0,0)
Radius is r^2 = 49 => r = 7
Hope it helps .
1) -27+1÷ -2 = -26÷ -2 =13
2) 60/-10 = -6
