What is the surface area of the box
Elena-2011 [213]

Answer:

<u>360 in²</u>

Step-by-step explanation:

Surface Area of the box = 2(lb+bh+hl)

                                        = 2(12×6 + 6×6 + 6×12)

                                        = 2(72 + 36 + 72)

                                        = 2(180)

                                        = <u>360 in²</u>

<u />

Therefore D is the right answer.

Solve the congruence 169x 25 (mod 330)
DIA [1.3K]

First solve the congruence 13y\equiv1\pmod{330}. Euclid's algorithm shows

330 = 25 * 13 + 5

13 = 2 * 5 + 3

5 = 1 * 3 + 2

3 = 1 * 2 + 1

=> 1 = 127 * 13 - 5 * 330

=> 127 * 13 = 1 mod 330

so that y=127 is the inverse of 13 modulo 330. Then in the original congruence, multiplying both sides by 127 twice gives

127^2\cdot13^2x\equiv127^2\cdot5^2\pmod{330}\implies x\equiv127^2\cdot5^2\equiv403,225\equiv295\pmod{330}

Then any integer of the form x=295+330n is a solution to the congruence, where n is any integer.
