Answer:

Step-by-step explanation:

Hello!

(x + 1)(x + 3) + (x + 2)(x + 4)

x*x = x²

x*3 = 3x

1*x = x

1*3=3

x*x=x²

x*4 = 4x

2*x= 2x

2*4 = 8

x²+3x+x+3+ x² + 4x+ 2x+ 8=

2x² + 10x+ 11

likoan [24]

Answer:

$My~gain~in~that~year~was~\$176.5$

Step-by-step explanation:

$Greetings!$

$I'm~Isabelle~Williams~and~will~be~answering~your~question!$

$I~have~\$1,500 ~in ~my ~investment~ account.~ Rate~ of~ interest ~for~ a\\ ~year~ in~ my ~investment~account = 8.5\$$

$So,~ the~ amount~ of~ money~ I~ am ~making~ on ~my ~investment ~in ~a ~year:$

$=\$\frac{1500\times 8.5}{100}$

$=\$127.5$

______________________________________________________

$I ~owe~ \$ 1600 ~on~ a ~credit~ card .~ Rate ~of ~ interest ~a ~year ~on~ this~ credit\\ card ~debt, = 19 \%$

$So,~ the~ money~ I~ am~ paying~ in~ interest ~in~ a~ year~ on~ my~ card~is:$

$=\$\frac{1600\times 19}{100}$

$=\$304$

______________________________________________________

$Since, ~neither~ I ~withdraw ~money~ from ~my~ investment~ account ~ except~ the\\ ~interest~ nor~ I ~pay~ my~ whole ~credit~ card ~debt~ except ~the ~interest,~ so,~ my~ gain~\\ in~ that~ year:$

$= \$ (127.5 - 304)$

$=\$176.5$

$Hope~my~answer~helps!~Have~an~amazing~day~ahead!$

The slope and y intercept

Fudgin [204]

Answer:

the y intercept is 5 because the line passes through 5 on the y axis. Now to find the slope, pick two points where the line hits directly on the corner of the grid squares. pIck 2 of those and count the squares up till you are lined up with your other point then count over and get another number. Put the number going up over the number going down like x/y and you'll have your answer. ( simplify it if you can.(-2,3) and (0,5) are a good place to start. The answer should be 2/3. Hope this helped and God bless!
