Answer:

x=1056.25

Step-by-step explanation:

(2x)(2x)(55)=(65)(65)(55) Multiply

4x(55)=232375 Divide 55 from each side

4x=4225 Divide each side by 4

x=1056.25

Answer:

x = 30

Step-by-step explanation:

Since the triangles are similar, that is

ΔABC and ΔDEC

The 3 angles in ΔDEC sum to 180°, thus

∠C + ∠D + ∠E = 180°, that is

55° + 65° + ∠E = 180°

120° + ∠E = 180° ( subtract 120 from both sides )

∠E = 60° and

∠E = ∠B = 2x = 60 ( divide both sides by 2 )

x = 30

How do you convert powers to the same base if the bases don't have common factors?

Yuri [45]

Answer:

6²

Step-by-step explanation:

Use the rule of exponents ...

(a·b)^c = a^c·b^c

Your expression has a=3, b=2, c=2.

3²·2² = (3·2)² = 6²

_____

If you want to get more sophisticated than that, logarithms can get involved.

$3^2\cdot 2^2=10^{2\log{(3)}+2\log{(2)}}\approx 10^{1.5563025}$
