Answer:21
(7*12)/4
Step-by-step explanation:
You have to look up how many miles are in one km.
You need that number to solve this problem.
<u> 1 km = about 0.62137... mile</u> (rounded)
160 km = (160) x (0.62137) = <em>99.419 miles</em> (rounded)
Answer:
(4a - 9)(4a + 9)
Step-by-step explanation:
Every value in the equation has a square root
The square root of 16 is 4
The square root of a^2 is a
The square root of 81 is 9.
To factor you split the equation by the square roots. For 81, since the original value is negative, one of the roots must be negative so when you multiply it back out to the original, it stays the same.
You can check your answer this way too.
(4a -9)(4a + 9)
= 16a^2 + 36a - 36a - 81
= 16a^2 - 81
I hope this helps!
Step-by-step explanation:
Option A is the correct answer
f(x)=8x+2
put x=-4
then out =8(-4)+2 = -32+2= -30
Okay we'll start easy
46*93
We will take 6*3 which is 18.
40*3 which is 120
6*90 which is 540
40*90 which is 3600
Now add up those
18+120+540+3600 which is 4278
So the missing numbers.
3._00 is going to be 3600
5_0 is going to be 540
_20 is going to be 120
1_ is going to be 18
4._78 is going to be 4.278
Hope this helped. ^~^
