= -2
= 1
= 5
= -2
substituting the values :
m = 
m =
Answer:
ABOUT 4000
Step-by-step explanation:
Answer:
Width = 3 feet
Length = 7 feet
Step-by-step explanation:
x represents the width of doghouse so,
Width = x
Length is 4 times more than its width
Length = x+4
Area of doghouse = 21 square feet
We know
Area of rectangle = Length * Width
21 = (x+4)*x
21 = x^2+4x
=> x^2+4x-21=0
Solving the above quadratic equation by factorization to find the value of x
x^2+7x-3x-21=0
x(x+7)-3(x+7)=0
(x+7)(x-3)=0
x+7 =0 and x-3=0
x= -7 and x =3
Since the width of rectangle can never be negative so, x=3
Width =x = 3 feet
Length = x+4 = 3+4 = 7 feet
Answer:
#1. Peng spent $48,918.
#2. The farmer had $10,660 at first.
#3. 2,160 minutes
Step-by-step explanation:
#1. (26 × $1,334) + (19 × $749)= $48,918
#2. 26 × 410 + 162= $10,660
#3. 2 ×(9 + 6 + 9 + 6)×12 ×3= 2×30×12×3= 2× 360 × 3= 720 × 3= 2,160 minutes
