Step-by-step explanation:
All these fancy terms is confusing. We just need to substitute the original equations into the final problem statement.

We can then substitute 100 for x and solve.

I'm pretty sure it's
q= 4(9)+4(6)
This is true, since both are quadrilaterals, so they have 4 sides and therefore 4 angles. There are 9 rhombuses, so each has 4 angles. This would mean you'd have to multiply each quadrilateral by 4 to find your answer.
I hope this helps a little.
(x²+5)½ + (x²+5)³/²
->(x+√5) +(x³+√125)
->(x+√5)+(x³+5√5)
->x+x³+√5+5√5
->2x³+6√5
->2(x³+3√5)
Answer:
76 is already in the simplest form. It can be written as 1.166667 in decimal form (rounded to 6 decimal places).
For this question, it would be most effective to use an algebraic expression to more easily show what the question is asking. If we use the variable "k" to show the distance in km that he cycled on Sunday, we know that the amount he cycled on Saturday equals k + 12, and the amount that he cycled on the weekend should be the amount of Saturday plus the amount of Sunday. If we write this as an equation we say:
k + k + 12 = 38
=> 2k + 12 = 38
Now we can just rearrange and solve for k:
=> 2k = 26
=> k = 26/2 = 13
Therefore Patrick cycled 13km on Sunday
To solve the answer, we just add 12km to the value for Sunday like so:
12 + 13 = the amount he cycled on Sunday
Hope this helped, remember to please try and understand the maths as well as the answer :))
