Answer:
80
Step-by-step explanation:
7-(5-3(2+6(2^2)))
When a question has multiple signs, the rule of BODMAS is used. That is, Bracket Of Division Multiplication Addition and Subtraction. The question above will therefore be solved in that order.
The first bracket, we have 2^2
That gives 4
Rewriting the question will give
7-(5-3(2+6(4)))
The question in the next bracket will follow
(2+6(4))
In this bracket too, we have the plus sign and the multiplication sign, so the multiplication will first be solved, them addition will follow.
(2+24)
(26)
Rewriting the question again, we have
7-(5-3(26))
And then, we have the last bracket
(5-3(26))
But we have both the Subtraction sign and the Multiplication sign in this bracket also, so the multiplication will first be solved, before the Subtraction.
(5-3(26))
(5-78)
(-73)
And lastly we have
7-(-73)
7+73
80
Answer:
5200
Step-by-step explanation:
2000 x 20% = 400
400 x 8 = 3200
2000 + 3200 =5200
The answer for:
20)
6x-7+6x³-4x-10x³-4-8x - 2x²= −43−22−6−11
19)
8u+6+7u+(-10) + (-5u) + 8= 10+4
Probably C)
it starts with 8-foot diameter, and it is supposed to get smaller
This is just a theory
