Answer:a
Step-by-step explanation:
I would explain but it’s a lot of work sorry
Answer:
There isn't one.
Step-by-step explanation:
The square root of a negative number is imaginary. There is no real number that is the square root of -3.24.
Answer:
y=-3x+5
Step-by-step explanation:
So, with perpendicular equations, you flip the slope, so 1/3 becomes 3/1, and make it negative, and if it is already negative, you make it positive. So, since we have the slope, move on to the b=y-mx, so b=-4-(3)(-3), multiply to get b=-4-(-9), which makes our y-int 5.
Answer:
x=9
<A=23
<B= 69
Step-by-step explanation:
1. 2x+5+3(2x+5)=92 2. 2x+5+6x+15=92 3. 8x+20=92 4. 8x=72 5. x=9
<A= 2(9)+5=18+5=23
<B= 3(2(9)+5)=3(23)=69
Answer:
Step-by-step explanation:
This can be simplified into
which is saying that you are taking the cubed root of each of those bases. The cubed root of 8 comes out evenly, to 2 (since 2*2*2 = 8). The cubed root of 320 is not so simple. To find it, find the complete factorization of 320. 320 factors to: 5 * 2*2*2*2*2*2 or
Split that 2^6 up into increments of 3's to make the simplifying a bit easier:
Because the index (the little number sitting in the bend of the radial sign) matches the power on both the 2's we can pull both the 2's out front, leaving:
but don't forget that we already found that the cubed root of 8 was 2, so multiply that 2 by the 4 to get:
