There are 60 minutes in one hour, thus, 45 miles per hour is 45 miles per 60 minutes, thus
triangle B. because congruent is supposed to be the same shape same size but triangle b is same shape but a different size
The easy way is to count outcomes. Of the 36 equally probable outcomes, 10 are less than or equal to 5, so the probability is 10/36 = 5/18.
Answer:
B
Step-by-step explanation:
f(x) = x²+49 , rewrite the equation
x² +7² =0 , to find the roots make f(x) =0 and subtract 7² from both sides
x² = -7², square root both sides
√x² =√-7², consider √-1 =i
x= ±7i
the roots are -7i and 7i
