Answer:
67
Step-by-step explanation:
Since the diagonals in a rectangle are congruent, AC=BD and
7x+18=10x-3
We need to separate x -- to do that, we can first subtract 7x from both sides, resulting in
18=3x-3
Next, add 3 to both sides to get
21=3x
Divide both sides by 3 to get
x=7
Then, we just plug x into 10x-3 to get BD = 7*10-3 = 67
Answer:
X=6
Step-by-step explanation:
First step isolate the variable;2x=12
Simplify;x=12/2=6
There is a difference of 123 square inches between the pizza box and the pizza.
18x18=324
pi8^2=201.0619
324-201=123
