Answer:
good job ig
Step-by-step explanation:
Let
x-------------> t<span>he width of each postcard
y-------------> the </span>the length of each postcard
we know that
A=12 in²
A=x*y-------> 12=x*y-------> equation 1
y=x+4-----> equation 2
<span>I substitute 2 in 1
</span>12=x*y----------> 12=x*[x+4]------> 12=x²+4x------> x²+4x-12=0
x²+4x-12=0
using a graph tool----> to resolve the second order equation
see the attached figure
the solution is
x=-6----> is not solution
x=2 in
y=x+4----> y=2+4-----> y=6 in
the answer isthe length of each postcard is 6 inthe width of each postcard is 2 in

Step-by-step explanation:
slope = Δy / Δx = -6/2 = -3
Answer:
q=-5
Step-by-step explanation:
8q+6=4q-14
Remove q from one side
8q+6=4q-14
-4q -4q
4q+6=-14
Remove 6 from both sides
4q+6=-14
-6 -6
4q=-20
Divide 4 to isolate q
4q/4=-20/4
q=-5
