Question 1:

5z – 9 = 36

5z = 45

z = $\frac{45}{5}$

z = 9

Hence, the answer is D.

Question 2:

5(2z + 4) = 0

10z + 20 = 0

10z = -20

z = $\frac{-20}{10}$

z = -2

Hence, the answer is A.

Question 3:

4a + 3(a + 1) = 24

4a + 3a + 3 = 24

7a = 21

a = $\frac{21}{7}$

a = 3

Hence, the answer is B.

Question 4:

3(4x + 5) = 12

12x + 15 = 12

12x = 12 - 15

12x = -3

x = $\frac{-3}{12} = - \frac{1}{4}$

Hence, the answer is A.

Question 5:

4x – 8 – 4x = 9

-8 ≠ 9

Hence, the answer is A.

Easy
remember
x^-m=1/(x^m)

so

f(-1)=4*7^-1=4*(1/(7^1))=4*(1/7)=4/7
f(2)=4*7^2=4*49=196

If m(x) = x2 + 3 and n(x) = 5x + 9, which expression is equivalent to (mn)(x)?

Ilia_Sergeevich [38]

For this case we have the following functions:
$m (x) = x ^ 2 + 3

n (x) = 5x + 9$
Multiplying both functions, we obtain an expression equivalent to (mn) (x).
We have then:
$(mn) (x) = m (x) n (x)
$
Substituting values we have:
$(mn) (x) = (x ^ 2 + 3) (5x + 9)
$
Rewriting the expression we have:
$(mn) (x) = (5x ^ 3 + 15x) + (9x ^ 2 + 27)

(mn) (x) = 5x ^ 3 + 9x ^ 2 + 15x + 27$
Answer:
An expression that is equivalent to (mn) (x) is:
$(mn) (x) = 5x ^ 3 + 9x ^ 2 + 15x + 27$
