Answer:
m=10
Step-by-step explanation:
hypotenuse is 15+5=20
to find shorter leg <em>m</em> divide the hypotenuse by 2
20÷2=10
Answer:
(8-3)(-7) =8×-7=-56 (-3)×(-7)=+21
Step-by-step explanation:
then -56+21= 77
$370.80 is the right answer
Let's call the width . Since the length is three more than the width, it is .
The area (which we know to be 70) is given by the multiplication of width and length:
To solve this equation, you can use the usual quadratic formula: given an equation , the two solutions are
which in your case becomes
So, two solutions are
Since we can't accept a negative length, we only accept the second solution.
So, the dimensions are 7 and 10
