Answer:
Because there are 4 ways to pick red then 4 (C)
combining like terms means to get rid of one factor on both sides of the equation.
Answer:
Width is 10ft and length is 6ft.
Step-by-step explanation:
The area of a shape is the amount inside a shape. It is found using multiplication or A = l*w. Since the width is w and the length is 4ft less than its width or w - 4, use these expressions in the area formula to find their amount.
Subtract 60 from both sides and factor the quadratic to solve for w.
Set each factor equal to 0 and solve.
w - 10 = 0 so w = 10
w + 6 = 0 so w = -6.
Since w represents a length or distance it cannot be negative, this means the width is 10. The length which is w - 4ft is 10 -4 = 6. The length is 6 ft.
Answer:
80%
Step-by-step explanation:
you divide 4 and 5. Which equals 80
Minus 6 both sides
7x²-x-6=0
hmm
using ac method we get
7x²-7x+6x-6=0
group
(7x²-7x)+(6x-6)=0
7x(x-1)+6(x-1)=0
undistribute
(7x+6)(x-1)=0
set to zero
7x+6=0
7x=-6
x=-6/7
x-1=0
x=1
x=-6/7 or 1
