Answer:

E) ab + ab

Step-by-step explanation:

The following options are missing:

A) 2a + b

B) ab + 2a

C) 5a + 6b

D) ab + 2b

E) ab + ab

An expression is even when f(x) = f(-x). In this case, the arguments are a and b. Let's suppose a = 1, b = 1 and analyze every option:

A) 2a + b = 2*1 + 1 ≠ 2*(-1) + (-1)

B) ab + 2a = 1*1 + 2*1 ≠ (-1)*(-1) + 2*(-1)

C) 5a + 6b = 5*1 + 6*1 ≠ 5*(-1) + 6*(-1)

D) ab + 2b = 1*1 + 2*1 ≠ (-1)*(-1) + 2*(-1)

E) ab + ab = 1*1 + 1*1 = (-1)*(-1) + (-1)*(-1) -> this is satisfied for every integers a and b

Semenov [28]

Answer: S = 20 lbs L = 45 lbs. Both answer have been rounded from below

Step-by-step explanation:

L+S = 65 lbs

55L + 65S = 3774 lbs

55L+55S = (65)(55) = 3,575 lbs

10S = 199 lbs

S = 19.99 (round to 20)

L + S = 65

L + 19.99 = 65

L = 45.01 (round to 45)

2. The number of nickels that Christine has is

aev [14]

Answer:

The number of nickels is 15

The number of Dimes is 3

Step-by-step explanation:

Let the number of dimes Christine has be d

The number of nickels with christine be n

Then the number of Nickels Christine has will be

n = 5d ----------------------------------(1)

Now The total value of both dimes and nickels is = $1.05

This can be represented as

5n +10d = 105 (in cents)

From eq(1)

5(5d) + 10d = 105

25d+10d = 105

35d = 105

$d = \frac{105}{35}$

d = 3----------------------------------(2)

Substituting (2) in (1), we get

n = 5(3)

n = 15
