Answer:
11x-1
Step-by-step explanation:
Area =length x width
so multiply (2x+3) and (3x+1) to get 11x-1
The simplification of the given algebraic expression is;
yz = (z + 1)/z(z - 1)
<h3>How to simplify algebraic expressions?</h3>
We are given y left parenthesis z right parenthesis which is expressed as; yz
Now, we are given the algebraic expression that yz equals space fraction numerator z squared minus 1 over denominator z left parenthesis z minus 1 right parenthesis squared end fraction
z squared minus 1 over denominator z left parenthesis z minus 1 right parenthesis squared end fraction is expressed as; (z² - 1)/z(z - 1)²
Thus, our main expression is;
yz = (z² - 1)/z(z - 1)²
Factorizing the numerator and denominator gives;
yz = (z + 1)(z - 1)/z(z - 1)(z - 1)
(z - 1) is common to both numerator and denominator and as such, we now have;
yz = (z + 1)/z(z - 1)

Answer:
215 minutes
Step-by-step explanation:
Let
Number of days she rode for 35 minutes = x
Number of days she rode for 55 minutes = y
Total time spent riding her bike = 35x + 55y
x = Monday + Wednesday + Saturday
x = 3 days
y = Tuesday + Thursday
= 2 days
Substitute into the equation
Total time spent riding her bike = 35x + 55y
= 35(3) + 55(2)
= 105 + 110
= 215 minutes
It would round to <span>7,464,000.55000</span>
