Question

Perform the indicated computation. Write the answer in scientific notation. 12 x 10^4/ 3 x 10 ^-2


A. 8 x 102
B. 4 x 106
C. 4 x 102
D. 8 x 106

Answer 1

2 . Find the product.

(7x - 6)2

A. 49x2 + 36
B. 49x2 - 84x + 36
C. 7x2 - 84x + 36
D. 7x2 + 36

Answer 2

For the second one, u distribute the ^2 so you would have 49x^2 - 36

Answer 3

12 x 10^4/ 3 x 10 ^-2 \[\Large \frac{ 12 \times 10 ^{4} }{ 3 \times 10 ^ {-2} } = \frac{ 12 }{ 3 } \times \frac{ 10 ^{4} }{ 10 ^ {-2} }\]

Answer 4

use \[\Large \frac{ x^a }{ x^b } = x^{a-b}\] so the \[\Large \frac{ 10 ^{4} }{ 10 ^ {-2} } = 10^{4- (-2)}\]
(that is not the final answer)

Answer 5

@Rexy705 that's not quite correct.
\[\Large (7x - 6)^2 = (7x- 6) (7x-6)\]now simplify that

Answer 6

oh that's right that totally slipped my mind =P

Answer 7

And then u would use foil

Answer 8

could you help me with another please @agent0smith ???

Answer 9

add or subtract
a. 2x - 16 / (x+2) ( x-2) b. 2/(x+2) (x-2) c . 2x-4/(x+2) ( x-2) d. 2x+16//(x+2)(x-2)
