Which expression is equivalent to 486 – 9 + 6 + 33 × 2?

549

Step-by-step explanation:

Remember PEMDAS (this is the order of operations).

P = Parentheses

E = Exponents

M = Multiplication

D = Division

A = Addition

S = Subtraction

So, lets do multiplication first.

33*2 = 66

So, our new expression is 486 - 9 + 6 + 66.

Remember that addition and subtraction are reversible.

486 - 9 = 477

477 + 6 = 483

483 + 66 = 549

404

Step-by-step explanation:

P-parenthesis

E-exponents

M-multiplication

D-division

A-addition

S-subtraction

486-9+6+33*2

486-9+6+66

486-81=404

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
