31.5
because 3 gallons are lost per minute so 3 x 10.5= 31.5

f(x) = y, when the graph touches the y-axis, x = 0.
So the ratios are 4 to 5 to 5 to 8 to 9 to 9
that means that the first 2 sides can be simplified to 4 to 5
therefor the whle sum is all the units added up
4+5+5+8+9+9=40
720=40 units
divide by 40
18=1 unit
solve for each unit
we have
4 units
5 units
8 units
9 units
4 times 18=72
5 times 18=90
8 times 18=144
9 times 18=152
the angles are
72,90,90,144,152,152
Answer:
9. 2a + 14
10. 7h - 70
Step-by-step explanation:
(2 x a ) + ( 2 x 7 )
(7 x h ) - ( 7 - 10 )
