Simplify the given expression. (18+ - 8)2

JulsSmile [24]

Answer:

Step-by-step explanation:

Our expression:

2 * (18 + - 8)

Plus then minus (+ -) is the same as just minus ( - )

Some examples:

1 + (+ 1) = 2

1 + (- 1) = 0

1 - (+ 1) = 0

1 - (- 1) = 2

Thus, 18 + - 8 is the same as 18 - 8

2 * (18 + - 8) =

= 2 * (18 - 8) =

= 2* (10) =

= 2 * 10 =

= 20

Which expression is not equivalent to (x + 4)(x – 3)?

Digiron [165]

Answer:

A) x² + 7x - 12 is NOT equivalent to the expression.

Step-by-step explanation:

1) expand by distributing terms.

${x }^{2} - 3x + 4(x - 3)$

2) Expand by distributing terms.

${x}^{2} - 3x + 4x - 12$

3) Collect like terms.

${x}^{2} + ( - 3x + 4x) - 12$

4) Simplify.

${x}^{2} + x - 12$

The second equation are equivalent to the equation. but the first equation is not equivalent to the main equation.

The next three terms in the sequence

Nookie1986 [14]

The next three terms are 2, 1/2, 1/4

You take 1/2 of each previous term to get the next term, which means this sequence is geometric (first term is 4, common ratio is 1/2)
