Question

I need help please help me I need help on q18 please I need q18 right I need a smart person

Answer 1

Step-by-step explanation:

50x² + 250 = 40x² + 350

If the charge the same amount then the polynomials they use to determine their prices be equal

10x² + 250 = 350

subtract 40x² on both side

10x² = 100

x² = 10

x = 3.2

Answer 2

Answer:

1)50(6)²+250

=50×36+250

=1800+250

=2050

2)40(5)²+350

= 40×25+350

=1000+350

=1350

3)

50x²+250=40x²+350

-40x²-250 -40x²-250

_______________

$\frac{10x {}^{2} }{10} = \frac{100}{10}$

$x {}^{2} = 10 \\ \sqrt{x {}^{2} } = \sqrt{10} x = 3.2ft$

4)

$40( \sqrt{10} ) {}^{2} + 350 = 750$
