Well, following the order of PEMDAS, I got choice B. 52
For instance, when you plug in 5 for x, you get F(5)=2(5)^2+2.
Moreover, following PEMDAS, you're supposed to solve what's inside the parenthesis, but since there is no operation going on inside the parenthesis, then you simple move on to the exponent.
In this case, you square the number 5, which gives you F(5)=2(25)+2
After that, you Multiply (letter M in PEMDAS). This results in F(5)=50+2.
Finally, you add them, which results in F=52.
By the way, I noticed a mistake in your work. When multiplying 2 by 5, the answer is 10, not 20.
Anyway, hope this helped! :-)
Ricky jogged 6 miles on tuesday and 6 miles on friday
<em><u>Solution:</u></em>
Given that,
Rick jogged the same distance on tuesday and friday
Let "x" be the distance jooged on each tuesday and friday
He also jogged for 8 miles on sunday
Total of 20 miles for the week
Therefore, we frame a equation as,
total distance jogged = miles jogged on tuesday + miles jogged on friday + miles jogged on sunday
20 = x + x + 8
20 = 2x + 8
2x = 20 - 8
2x = 12
x = 6
Thus Ricky jogged 6 miles on tuesday and 6 miles on friday
Answer:
3rd degree trinomial
Step-by-step explanation:
the highest power is 3 and there are 3 terms so its a 3rd degree trinomial
Answer:
-9
Step-by-step explanation:
Simplify the following:
-6×(-2)/4 (-3)
-6×(-2)/4 (-3) = (-6 (-2) (-3))/4:
(-6 (-2) (-3))/4
The gcd of -2 and 4 is 2, so (-6 (-2) (-3))/4 = (-6 (2 (-1)) (-3))/(2×2) = 2/2×(-6 (-1) (-3))/2 = (-6 (-1) (-3))/2:
(-6-1 (-3))/2
(-6)/2 = (2 (-3))/2 = -3:
--3 (-3)
-3 (-1) = 3:
3 (-3)
3 (-3) = -9:
Answer: -9
Answer:
y = 20 x = 6
Step-by-step explanation:
1 (3x+ 2y = 58 ------------> -3x + -2y = -58
1x + 2y = 46 --------------> 1x + 2y = 46
____________
-2x = -12
-----------------
-2x -2x
x = 6
3(6) + 2y = 58
18 + 2y = 58
-18 -18
------------------
2y = 40
----- -----
2y 2y
y = 20
