Answer:
C. 65
Step-by-step explanation:
Compare to the standard form ...
ax² +bx +c
to find the values of a, b, c. They are ...
a=2, b=3, c=-7
The discriminant is ...
d = b² -4ac
d = (3)² -4(2)(-7) = 9 +56
d = 65 . . . . . . matches choice C
Answer:
16w+40
Step-by-step explanation:
To simplify this equation you have to use the distributive property first. This means you multiply 4 by everything in the first set of parentheses and you multiply 6 by everything in the second set of parentheses. This leaves you with 4w+16+24+12w.
Next, you combine like terms by adding 4w and 12w to get 16w, and 16 and 24 to get 40.
So, your final answer is 16w+40.
265,888 rounded to the nearest ten thousand is 70,000.
