Answer:
Step-by-step explanation:
Get the perimeter of the each shape and add it all up to get the total fencing material required.
2 square flower beds = 2 x 4a = 8a
1 rectangular play ground = 2l + 2w
total fencing material = 8a + 2l + 2w
Answer:
A then B
Step-by-step explanation:
1440≈1,000, and 1,000=10^3
1000000/1440≈700, and 700≈1,000. 1,000=10^3
The answer is <span>1.0737
you can use the calculator though</span>
Original equation
<span>√x+10-9 = -7
</span>Isolate
<span>√x+10 = 9-7
</span>
<span>√x+10 = 2
</span> Raise both sides to the second power
<span> (√x+10)2 = (2)2
</span> After squaring
<span> x+10 = 4
</span>
x + 6 = 0
so the answer is x=-6
