-320. The negative sign represents loss. In all of the other cases, values are either being added or not changed at all.
The four angles inside EVERY four-sided figure add up to 360 degrees, no matter what the shape of the figure is.
"Four obtuse angles" means "four angles of more than 90 degrees each".
(four times more-than-90) = more than 360
so NO 4-sided figure can have four obtuse angles inside it.
Answer:
12a+60 i think lol
Step-by-step explanation:
this is how i did it though:
12(a+b)
12a+60
Answer:
There is no solution to the problem
Step-by-step explanation:
In order to find the solutions to the problem you can write the situation in an algebraic form.
You have that a number is equal to twice a smaller number plus 3. This can be written as follow:
(1)
where x is the number and y is the smaller number
Furthermore, the same number x is equal to twice the sum of the smaller number and 1, which can be written as follow:
(2)
To find the solution you equal the equation (1) with (2), and you solve for y:


You obtain an inconsistency, hence, the situation of the problem does not have solution
X/100 = 52/260
100•52=5200
5200/260 = 20
