You find the volume of the flower bed (4 times 25 time 6) this is 600. but you then realize that you need to convert the 6 inches into ft. so you do 25 times 4 /2 which is 50. 50/9 is rounded up to 6. Just notes: Although, when you do this, your units are in ft squared. you need to get them into yards. there are 3 feet in one yard. So, divide 600 by 9. (you need to multiply 3 times 3 to cancel out the ft squared). your answer is a
Answer:
c. none of the above
Step-by-step explanation:
They multiplied 3 by itself 4 times, so it’s 3^4

since -x^2+x+19=y

</span>
x=-x^2+x+19+80
<span>
</span>
x=-x^2+x+99
<span>
</span>
0=-x^2+99

x^2=99
x=3√11
x=y+80
3√11=y+80
minus 80 both sides
-80+3√11=y
x=3√11
y=-80+3√11
solution
(x,y)
(3√11,-80+3√11)
