Fill in the blank spaces using the names of the two-dimensional figures listed below.
S_A_V [24]

Explanation:

There are many versions of the taxonomy diagram for quadrilaterals. The details depend on the particulars of the definitions you use. Here, we'll say a parallelogram is a subset of trapezoids. Not all authors would agree.

(2) kite -- two pairs of adjacent same-length sides

(3) trapezoid -- (at least one) pair of parallel opposite sides

(4) parallelogram -- opposite sides are parallel

(5) rhombus -- all sides the same length (and opposite sides parallel)

(6) rectangle -- parallel opposite sides and right angles

(7) square -- same-length parallel opposite sides and right angles

What values of a and b make the equation true? sqrt(648)=sqrt(2^a•3^b)
Anuta_ua [19.1K]
ANSWER

The value of a and b are:

a=3,b=4

EXPLANATION

The expression given to us is

\sqrt{648} = \sqrt{ {2}^{a} \times {3}^{b} }

We square both sides of the equation to obtain

648= {2}^{a} \times {3}^{b}

We now find the prime factorization of 648 to obtain,

{2}^{3} \times {3}^{4} = {2}^{a} \times {3}^{b}

We now compare the exponents on both sides of the equation to obtain,

a=3,b=4

Therefore the correct option is C
