Step-by-step explanation:
15 minutes is
15 minutes * 1 hour/ 60 minutes = 1/4 hour

10 km/ hour * 1/4 hour = 10/4 km = 2.5 km
Joe has 82 yards of cotton. His friend has 104 more
104 + 82 = 186
186 yards is how much cotton yarn his friend has
hope this helps
The quadratic equation would be;
x2+15x-2=0
Working:
Assuming the area around the painting i.e the frame, has a uniform thickness, then;
Length of painting and frame = 8+x
Breadth of painting and frame= 7+x
The area from above step gives;
A= LxW
A= (8+x)(7+x)
On expanding, 56+8x+7x+x2
On simplifying,
56+15x+x2. This should be equal to 58.
58=x2+15x+56
Taking 58 to the other side,
x2+15x-2=0
