Write the expression in simplest form.<br> ( 4 = + 3) – 2(- \ - - })= 0
Dimas [21]

Answer:

3^x=9^{x+5}

Step-by-step explanation:

3^x=9^{x+5}

x^2-x-6=0

x^4-5x^2+4=0

\sqrt{x-1}-x=-7

\left|3x+1\right|=4

\log _2\left(x+1\right)=\log _3\left(27\right)

3^x=9^{x+5}

If request to solve;

\mathrm{Convert\:}9^{x+5}\mathrm{\:to\:base\:}3

9^{x+5}=\left(3^2\right)^{x+5}

\mathrm{Solve\:}\:x=2\left(x+5\right):\quad x=-10

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.
