Select the correct answer.

Paladinen [302]

Answer:

Step-by-step explanation:

$2x^2+16x-8=0$

Simplify:

$x^2+8x=4$

Rewrite in the form $(x+a)^2=b$ :

$x^2+8x=4$

Add $4^2$ to both sides:

$x^2+8x+4^2=4+4^2$

$x^2+8x+4^2=20$

$\left(x+4\right)^2=20$

$x+4=\sqrt{20}$ or $x+4=-\sqrt{20}$

x = -4± $\sqrt{20}$

x= -4± $2\sqrt{5}$

CaHeK987 [17]

Answer:

least number of quilts is gonna be 10

Step-by-step explanation:

ok...so profit = revenue - expenses

n = # of quilts

revenue : (the money made from the quilts)

she sold each quilt for 35 bucks......35n

expense : (the money Norma spent on the materials)

the cost of fabric is 13.55 per quilt......13.55n

so ur expression is :

revenue - expenses

35n - 13.55n <==== this is part A

==========================

she wants to make a profit of 200...

P = revenue - expenses

200 = 35n - 13.55n

200 = 21.45n

200 / 21.45 = n

9.32 = n.......gonna have to round up to 10 <==== part B

ok...so 9 quilts is not gonna be quite enough...so shes gonna have to make 10.
