Larry claims that (14 + 12) × (8 + 12) and (14 × 12) + (8 × 12) are equivalent because they have the same digits and the same op
FromTheMoon [43]

Answer:

(14+12)\times (8+12) > (14\times 12)+(8\times 12)

Step-by-step explanation:

First let us evaluate the value of both the expressions.

(14+12)\times (8+12) = 26\times 20 = 520

(14\times 12)+(8\times 12) = 168 + 96 = 264

a) Hence, Larry's claim that both the expressions are equivalent is wrong.

The evaluation of the expressions have been shown above. The second expression was obtained by swapping the addition and multiplication order and that created the difference.

b) Clearly,

520 > 264

Therefore,

(14+12)\times (8+12) > (14\times 12)+(8\times 12)

(14+12)\times (8+12) is greater by the expression  (14\times 12)+(8\times 12) by a value of 520 - 264 = 256.

PLEASE ANSWER ASSAP!!! IF CORRECT WILL GIVE BRAINLY!!!!! Which one of these relationships is different than the other three? Exp
Pavlova-9 [17]

Answer:

The relationship B is different than the other three, because it has a different proportionality constant.

Step-by-step explanation:

All available options show direct relationships, which are defined as follows:

y\propto x

y=k\cdot x (1)

Where:

x - Independent variable, dimensionless.

y - Dependent variable, dimensionless.

k - Proportionality constant, dimensionless.

We proceed to use the following strategy based on the proportionality constant, that is:

k = \frac{y}{x}

A different relationship must indicate a different proportionality constant:

Option A (x = 0.8, y = 4)

k = \frac{4}{0.8}

k = 5

Option B (x = 10, y = 55)

k = \frac{55}{10}

k = 5.5

Option C (x = 4, y = 20)

k = \frac{20}{4}

k = 5

Option D (x = 10, y = 50)

k = \frac{50}{10}

k = 5

The relationship B is different than the other three, because it has a different proportionality constant.
