The solution of the given equation is +9 and -9.

Step-by-step explanation:

Given,

g(x) = 7x^{2} =567

To find the solution of x.

7x^{2} = 567

or, x^{2} =\frac{567}{7}

or, x^{2} = 81

or, x = ±\sqrt{81} [ square roots has two values so we put ±]

or, x = ±9

Answer:

x = ±9

Step-by-step explanation:

7x^2=567

Divide each side by 7

7/7x^2=567/7

x^2 =81

Take the square root of each side

sqrt(x^2) = sqrt(81)

x = ±9

Slav-nsk [51]

Answer:

64 carnations and 16 roses.

Step-by-step explanation:

The events committee buys 80 flowers

The flowers are a combination of carnations and roses.

Each carnation costs $0.50 and each rose costs $2.50

The committee spends a total of $72

<u>Solution:</u>

<u />

Let there be  (c) carnations and (r) roses.

So,

c + r = 80 flowers

and $0.50c + $2.50 = $72

This forms a simultaneous equation:

c + r = 80 ... (i)

0.5c + 2.5r = 72 ... (ii)

Multiplying equation (i) by 0.5 and equation (ii) by 1 gives;

0.5c + 0.5r = 40 ... (i)

0.5c + 2.5r = 72 ... (ii)

Subtracting (i)  from (ii) gives;

0c + 2r = 32

2r = 32

r = 32 ÷ 2 = 16

Therefore, there are 16 roses

and 80 - 16 = 64 carnations
