2(x+1)^2 +4(x+1)+7 as a simplified polynomial

weeeeeb [17]

Answer:

2x^2+8x+15

Step-by-step explanation:

${2(x + 1)}^{2} + 4(x + 1) + 7$

$2({x}^{2} + 2x + 1) + 4x + 4 + 7$

$2 {x}^{2} + 4x + 2 + 4x + 13$

$2 {x}^{2} + 8x + 15$

PLEASE HELP<br> WILL GIVE BRAINLIEST FOR ANSWER AND EXPLANATION<br> I HAVE A TEST TOMORROW

I believe you just plug in the distance formula:
$25 = \sqrt{(y - 4) ^{2} + ( - 8 - 2) ^{2} }$
remove the radical by squaring both sides. then remove the exponents. you'll then have
$25 = (y - 4) + ( - 8 - 2)$
$25 = y - 4 - 10$
y equals 39. I'm not entirely sure about this. I hope I answered your question correctly
