I think it's equal to 1 because every expression with the exponent of zero is equal to 1, idk for sure though
Answer:
<h2>
6</h2>
Step-by-step explanation:
To find the width/length when you know the area and the length or width, you just divide the area by the known side.
45/7.5 = 6
Answer:
60 minutes
Step-by-step explanation:
to find this, we will first determine how long it takes austin to run one mile.
18 miles / 180 minutes
1 mile / 10 minutes
it takes austin to run 10 minutes to run 1 mile
now, we will multiply the number of minutes it takes by 6 to find how long it takes austin to run 6 miles.
1 mile / 10 minutes
6 miles / 60 minutes
it takes austin 60 minutes to run 6 miles
Answer:
a) x² +1
b) x² +25
Step-by-step explanation:
a) (x+i)(x− i)
= x² - ( i ) x + ( i ) x - ( i)²
= x² - i² ∵ i² = -1
= x² - (-1)
= x² +1
b) (x+5 i)(x− 5i)
= x² - ( 5 i ) x + ( 5 i ) x - ( 5 i)²
= x² - 25 i² ∵ i² = -1
= x² - 25(-1)
= x² +25
we can also solve
using identity
(a + b)(a - b) = a² - b²
= (x+5 i)(x− 5i)
= x² - (5 i)²
= x² - 25 i²
= x² +25
