Answer:
307 paces
Step-by-step explanation:
First, lets convert Robert's pace to metres. (cm > m)
75cm = (75/100)m
= 0.75m
Number of Full Paces = Length of Bridge / 1 Full Pace
=

See , we must have full paces, and in this case we are finding the minimum number of paces, so we will be looking at the lowest possible whole number, which in this case, is 307 paces.
I think the answer is B y= 3x-7
I don’t have time to explain it but hopefully someone else will, he answer is -13!
Step-by-step explanation:
a)
<u>g(3) = 9 </u>
b)
<u>g(-1) = 1</u>
c)
<u>g(-x) = x²</u>
d)
<u>g(2y) = 4y²</u>
e)
<u>g(1 + h) = 1 + h² + 2h</u>
<em>using</em><em> </em><em>the</em><em> </em><em>identity</em><em> </em><em>(</em><em>a</em><em> </em><em>+</em><em>b</em><em>)</em><em>²</em><em> </em><em>=</em><em> </em><em>a</em><em>²</em><em> </em><em>+</em><em> </em><em>b</em><em>²</em><em> </em><em>+</em><em> </em><em>2ab</em>
I would say A, because the other two equations are for area and volume. and circumference is the only one that is an actual line.
