3x + 2 = x + 4 ( x + 2 )

Step2247 [10]

Answer:

<h2>x = -3</h2>

Step-by-step explanation:

$3x+2=x+4(x+2)\qquad\text{use the distributive property}\ a(b+c)=ab+ac\\\\3x+2=x+(4)(x)+(4)(2)\\\\3x+2=x+4x+8\qquad\text{combine like terms}\\\\3x+2=(x+4x)+8\\\\3x+2=5x+8\qquad\text{subtract 2 from both sides}\\\\3x+2-2=5x+8-2\\\\3x=5x+6\qquad\text{subtract}\ 5x\ \text{from both sides}\\\\3x-5x=5x-5x+6\\\\-2x=6\qquad\text{divide both sides by (-2)}\\\\\dfrac{-2x}{-2}=\dfrac{6}{-2}\\\\x=-3$

Need help ASAP I’m about to go to sleep

Arlecino [84]

Answer:

A. $1852.50

Step-by-step explanation:

Principal amount= P= $3, 900

Rate= r = 19% = 0.19

Time (in years) = t = 2.5

<u>Amount after 2.5 years (A)</u>

$A = P(1+r t )$

$A = 3900 (1+ (0.19) 2.5)$

$A = 5,752.5$

Total interest in 2.5 years = A-P = 5752.5 - 3900 = 1852.50
