$\qquad\qquad\huge\underline{{\sf Answer}}♪$

Let's solve ~

$\qquad \sf \dashrightarrow \:f(x) = g(x)$

$\qquad \sf \dashrightarrow \:x + 2 = - {x}^{2} + 4$

$\qquad \sf \dashrightarrow \: {x}^{2} + x + 2 - 4 = 0$

$\qquad \sf \dashrightarrow \: {x}^{2} + x - 2 = 0$

$\qquad \sf \dashrightarrow \: {x}^{2} + 2x - x - 2 = 0$

$\qquad \sf \dashrightarrow \:x(x + 2) - (x + 2) = 0$

$\qquad \sf \dashrightarrow \:(x + 2)(x - 1) = 0$

Hence, x = -2 or x = 1

Factor out the GCF from the polynomial.<br> 18x^6+ 81x^5 - 63x^2 +45

kramer

Answer:

The GCF is 9

Step-by-step explanation:

In the given polynomial $18x^6+ 81x^5 - 63x^2 +45$ lets represent each term as its factors

$18x^6$ = $2 \times 3 \times 3 \times x \times x \times x \times x \times x \times x$

$81x^5$ = $3 \times 3 \times 3 \times 3 \times x \times x \times x \times x \times x$

$63x^2$ = $3 \times 3 \times 7 \times x \times x$

45 = $3 \times 3 \times 5$

The greatest common factors from each term are 3 , 3

Thus the GCF = $3 \times 3$ = 9

Dmitriy789 [7]

Answer:

x=6, x=0

Step-by-step explanation:

$(x - 3) ^{2}$ + $(y - 2) ^{2}$ = 25

$(x - 3) ^{2}$ + $(6 - 2) ^{2}$ = 25

x=6, x=0

2500$

Step-by-step explanation:

p-22/100*p=1950

(100-22)*p/100=1950

78p/100=1950

*100 *100

78p=195,000

:78 :78

p=2500
