Plug in the x+3 for y.
8x-x+3=12
7x=9
X=1.3
Then, y= -0.25
Answer:
68 inches
Step-by-step explanation:
P = 2 (L + W)
P = 2(4x+5 + 4x+5)
P = 2(8x + 10)
P = 16x + 20
If x= 3
P = 16(3) + 20
P = 48 + 20
P = 68 inches
0.03 you just times it by ten or if its a decimal take away the 0 infront of it
Answer:
length = 20cm
breadth = 8cm
Step-by-step explanation:
solution;
length(l) = x + 12
breadth(b) = x
perimeter (p) = 56 cm
we know that,
perimeter(p) = 2(l + b)
or, 56 = 2(x + 12 + x)
or, 56 = 2(2x + 12)
or, 56 = 4x +24
or, 56 - 24 = 4x
or, 32 = 4x
or, 32 / 4 = x
x = 8
now
putting the value of x in length and breadth
length = x+ 12
=8 + 12
=20cm
breadth = 8cm
The answer is (3,2)
To get this answer we either...
A) Multiply both coordinates by 1/3
or
B) Divide each coordinate by 3
9*(1/3) = 9/3 = 3
6*(1/3) = 6/3 = 2
