Answer:
A
Step-by-step explanation:
6/x* 5/(2x+1) = 30/ 2x^2+x
(4x^2+3) + (3x^2+8) = 7x^2+11
Hey there!
When you multiply across, you get the following product:
<span>
8 </span>× –<span>23 </span>× –<span>21 </span>× –<span>29
</span>–184 × –21 × –29
3864 × –29
–112,056
The sign will be negative.
Hope this helped you out! :-)<span />
T = 4.2m + 2.4
T is the total gallons
M is the minutes
{ x + 3 y = 7 * ( - 2)
2 x + 4 y = 8
{ - 2 x - 6 y = - 14
2 x + 4 y = 8
_______________
-2 y = - 6 * ( -1)
2 y = 6
y = 6 / 2
y = 3
For x :
2 x + 4 y = 8
2 x + 4 * ( 3) = 8
2 x + 12 = 8
2 x = 8 - 12
2 x = - 4
x = - 4 / 2
x = - 2
Solution: x = -2 and y = 3
hope this helps!
