Answer:
204m*squared
Step-by-step explanation:
(20m × 13m) - 8m × (13 - 6)m
= 260m - 56m
=204m*squared

The equation to represent the price is y = 190(1.15)x
<h3>What is equation?</h3>
An equation is a mathematical expression that contains an equals symbol.
Given:
price of silver has increased by 15% per year from 2000.
Price for silver bowl = $190.
Total increment= 100% + 15% = 115% = 1.15
The price of bowl after x years
y = 190*(1.15x)
y = 190(1.15)x

Answer and Step-by-step explanation:
4 hours on Monday, so subtract 4 from 16.
We get 12.
So now it says twice as many on Saturday as on Thursday
So two numbers that add up to 12, but one number is twice the other number, would be 4.
4 times 2 is 8, and 4 + 8 is 12. 12 + 4 = 16
8 is the answer.
Kyle works 8 hours on Saturday.
Since 8 is twice the amount of 4, and 8 + 4 + 4 equals 16.

Answer:
Step-by-step explanation:
So we have the expression:
For both the numerator and the denominator, factor out a 5:
The term in the numerator can be factored. This is the difference of two squares pattern:
Both layers have a 5(x+2). Cancel them, Since we know that x <em>cannot</em> be -2, we can safely do so:
And we're done!
Notes:
If we weren't told that x ≠ -2, then we cannot divide them because if x <em>did</em> equal -2, the equation would be undefined. However, since we were given that, we can simplify.
However, even if we weren't given x ≠ -2, we can <em>still</em> simplify, but we need to add the restraint ourselves. This must be done, or else the equation won't be correct.
