Answer:
dx+9x+16d^2 dont know it it helps any but i tried
Step-by-step explanation:
A= adult ticket c=child ticket
1. 6a+4c=88
12a+9c=186
2. so you need to multiply the top number by -2 so you can cancel out the 12a
-2(6a+4c=88)=. -12a-8c=-176
3. then you add them all together
12a+9c=186
-12a-8c=-176
——————————-
c=10
4. now you have to find ‘a’
6a+4(10)=88
6a+40=88
-40. -40
6a=48
divide both sides by 6
a=8
And your final answer should be (8,10)
hoped this helped:)
Answer:
(x-4) (x+1)
step by step explanation:,
Area = 14 x 4.5 = 63 m^2
area = 10 * 4 = 40/2 = 20
4*3 = 12/2 = 6
20+6 = 26 in^2
