Answer:

$x^{2}$ + 2xy + $y^{2}$

Step-by-step explanation:

(x + y)(x + y)

= (x + y)(x + y)

=(x)(x) + (x)(y) + (y)(x) + (y)(y)

= $x^{2}$ + xy + xy + $y^{2}$

= $x^{2}$ + 2xy + $y^{2}$

FOIL

first x*x = x^2

Outer x*y = xy

inner: y*x = xy

last y*y = y^2

add together

How would i anser this select all the ratios equivalent to 4:6

Natali5045456 [20]

If we try to simplify the ratio or try to multiply both by any number, we will get the equivalent ratio

Like :

$\frac{4}{6} \\$

Divide ( simplify ) by 2

$\frac{ \frac{4}{2} }{ \frac{6}{2} } \\ \\ \\ = > \frac{2}{3}$

Or multiply by any number,

$\frac{4}{6} \\ \\ \\ = > \frac{4 \times 2}{6 \times 2} \\ \\ \\ = > \frac{8}{12}$

From the example, 2 / 3 and 8 / 12 are equivalent ratios to 4 / 6

100% pure gold is 24 karat gold, which is too soft to be made into jewelry most call Jory is 14 karat gold proximally 58% gold 1

denis-greek [22]

Answer:

The amount of gold used in a 200 g 14 gold bracelet is 116 g.

Step-by-step explanation:

Since a 14 karat jewell is stated to have aproximally 58 % of it's weigh in gold we need to take the total weigh of the jewel in question and find that percentage of it's weigh. In order to find that percentage we'll first convert that number into a decimal, we do that by dividing it by 100, so we have 58% = 58/100 = 0.58 we can multiply this value by the weigh of the jewel to find the amount of gold used. So we have:

gold used = total weigh*0.58 = 200*0.58 = 116 g
