Cost, C = $28410.72
Step-by-step explanation:
We have, a concrete pillar has the shape of a cylinder.
Diameter of pillar is 8 m and ts height is 9 m
If concrete costs $87 per cubic meter, it is required to find the concrete cost for the pillar. For this lets find the area of cylindrical shape. So,
The cost of pillar at the rate of $87 per cubic meter will be :
Answer:
The correct form for each case is:
- a) 4 (5x + 6) = 20x + 24
- b) -5 (2x - 3) = -10x + 15
- c) 3 (9x + 2y) = 27x + 6y
Step-by-step explanation:
I'm gonna give you the reason for each case.
a) The original equation is:
Now, we're gonna solve the first part of the equation and comparate:
How you can see, the first part is different from the last number, for this reason, the mistake is the 6, then I change it by the 24.
b) The original equation is:
As the previous exercise, we're gonna solve the first part:
You must know that when you multiply two negative signs, the result is positive.
c) The original equation is:
But, this equation can be made in this form:
How you can see, the first part can't be operated or anything, the one form to operate this is removing the plus sign and operating like a multiply.
- 3 (9x + 2y) = 27x + 6y
- 27x + 6y = 27x + 6y

Answer:
£142 for 3 jumpers and 8 T-shirts
Step-by-step explanation:
Since the T-shirts cost £3.50 each and they are buy one get one free, when you buy 8 T-shirts you only pay for 4 of them.
£3.50(4) = £140 for the 8 T-shirts
Since you bought 3 jumpers with a buy 3 for £2 sale, the 3 jumpers cost £2.
Add the amount of money all together to find the total cost of the T-shirts and jumpers.
£140 + £2 = £142
