If the 2nd and 5th terms of a

blagie [28]

Answer:

45

Step-by-step explanation:

The n th term of a GP is

$a_{n}$ = a $r^{n-1}$

where a is the first term and r the common ratio

Given a₂ = 6 and a₅ = 48, then

ar = 6 → (1)

a $r^{4}$ = 48 → (2)

Divide (2) by (1)

$\frac{ar^4}{ar}$ = $\frac{48}{6}$ , that is

r³ = 8 ( take the cube root of both sides )

r = $\sqrt[3]{8}$ = 2

Substitute r = 2 into (1)

2a = 6 ( divide both sides by 2 )

a = 3

Thus

3, 6, 12, 24 ← are the first 4 terms

3 + 6 + 12 + 24 = 45 ← sum of first 4 terms

What value of x makes the

loris [4]

Answer:

$x = -12$

Step-by-step explanation:

<u>Step 1: Add 1/4x to both sides</u>

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

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

$-12 = \frac{5}{4}x + 3$

<u>Step 2: Subtract 3 from both sides</u>

$-12 - 3 = \frac{5}{4}x + 3 - 3$

$-15 = \frac{5}{4}x$

<u>Step 3: Multiply both sides by 4/5</u>

$-15*\frac{4}{5}=\frac{5}{4}x * \frac{4}{5}$

$-12 = x$

Answer: $x = -12$
