Step-by-step explanation:
it is basically counting by 2s but rather by 20s.
20, 40,60,80
all you do is add a 9 at the end.
Answer:
x=2
Step-by-step explanation:
Original width = 6
New width 6+x+x
Orignal length 12
New length 12+x+x
A = l*w
160 = ( 6+2x) ( 12+2x)
Factor
160 = 2( 3+x) 2(6+x)
Divide each side by 4
40 = (3+x) (6+x)
FOIL
40 = 18+ 6x+3x+ x^2
40 = 18 +9x+x^2
Subtract 40 from each side
0 = x^2 +9x -22
Factor
0 = (x +11) (x-2)
Using the zero product property
x +11 =0 x-2 =0
x= -11 x=2
Since we cannot have a negative sidewalk
x =2
Answer: (5,0)
Step-by-step explanation:
x - 3y =5 -----------(1)
2x + y = 10 ----------(2)
By elimination method, multiply eqn(1) by 2
2x - 6y = 10 ------------(3)
eqn(3) - eqn(2)
-7y = 0
Divide bothside by -7
y= 0
Now, we substitute the value of y in eqn(1)
x - 3(0) = 5
x - 0 = 5
x=5
Therefore,x=5 and y=0
