Evaluate 2(s+t)³-6 when s =3 and t = 2?

Answers

Answer:

244

Step-by-step explanation:

We will see that the evaluated expression is equal to 244.

How to evaluate an expression?

Evaluating an expression just means that we need to replace the variables by the wanted numbers.

Here we need to evaluate:

2(s+t)³-6

In t = 2 and s = 3, replacing these in the expression we get:

2(3+2)³- 6 = 2*(5)³ - 6 = 2*125 - 6 = 244

So the evaluated expression is equal to 244.

HELPPPPPP ANYBODY KNOW????

Answers

All the angles should add up to 360
So you know 1 is 110
But you also know 1 is 90 because of the square so you know half is equal to 200
So you are working with 160=360-200
So now you look at the number left and say what number can be doubled and still have enough left over to add 10.
So I guess 50 times 2 is 100
And 50 plus 10 is 60
So check does this add up to be 160?yes
So x is 50
Good luck
