Answer:
10 19/10 meters
Step-by-step explanation:
Step one:
given data
let the amount of string used for the soccer field be x
and the amount used for coach spot be y
Also, let the total string used be represented as T
Step two:
Hence the expression for the total is
T= x+y
T= 9 1/2+ 2 2/5
T= 9.5+ 2.4
T= 11.9
or
T= 119/10 meters
or
T= 10 19/10 meters
Answer:
20
Step-by-step explanation:
(6x3=18) (6x1/3=2) (18+2=20)
The Greatest Common Factor of that expression is z. Hope this helps
Answer:
3.2
Step-by-step explanation:
Answer:
9 inches
Step-by-step explanation:
Area of rectangle= length ×width
Let the length of the rectangle be x inches.
Width of rectangle= (x +2) inches
<em>since</em><em> </em><em>the</em><em> </em><em>width</em><em> </em><em>is</em><em> </em><em>2</em><em> </em><em>more</em><em> </em><em>than</em><em> </em><em>the</em><em> </em><em>length</em><em>.</em>
63= x(x+2)
63= x(x) +2x
<em>Bringing</em><em> </em><em>constant</em><em> </em><em>to</em><em> </em><em>one</em><em> </em><em>side</em><em>,</em>
x² +2x -63= 0
(x +9)(x-7) = 0 (<em>factorise</em><em>)</em>
x+9= 0 or x-7= 0
x= -9 or x= 7
(reject)
width of rectangle
= 7+2
= 9 inches
*We reject x= -9 since the length of the rectangle cannot be a negative number.
