Answer:

7 + 42i.

Step-by-step explanation:

u v = 7i(6 - i)

=  42i - 7i^2    But i^2 = -1 so:

=  42i - 7(-1)

=     7 + 42i.

QUESTIONS
Arlecino [84]

Answer:

Number of  jars can be filled from 15kg of the salt = 468 or 469 jars (Approx.)

Step-by-step explanation:

Given:

Amount of salt containing in jar = 32 gram

Total amount of salt in jar = 15 kg

Find:

Number of  jars can be filled from 15kg of the salt

Computation:

Total amount of salt in jar = 15 kg

Total amount of salt in jar (in grams) = 15 x 1000 g

Total amount of salt in jar (in grams) = 15,000 g

Number of  jars can be filled from 15kg of the salt = Total amount of salt in jar (in grams) / Amount of salt containing in jar

Number of  jars can be filled from 15kg of the salt = 15,000 / 32

Number of  jars can be filled from 15kg of the salt = 468.75

Number of  jars can be filled from 15kg of the salt = 468 or 469 jars (Approx.)

What is the definition of property of equality
AnnZ [28]

<u><em>Answer: Addition property of equality, Subtraction property of equality, Multiplication property of equality, and Division property of equality.</em></u>

Step-by-step explanation:

Addition property of equality is adding the same number to both sides of an equation does not change the equation.

a+c=b+c

Example: t-6=13

add 6 both sides of an equation.

t-6+6=13+6

answer: t=19

________________________________________________________

Subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.

a-c=b-c

11=x+5

switch sides of equation

x+5=11

subtract by 5 both sides of an equation.

x+5-5=11=5

answer: x=6

___________________________________________________________

Multiplication property of equality is multiplying both sides of an equation by the same number does not change the equation.

a*c=b*c

t/5=3

example:

5/1*t/5=3*5

then multiply on the right side.

t=3*5

answer: t=15

______________________________________________________

Division property of equality is dividing both sides of an equation by the same non-zero number does not change the equation.

a/c=b/c for c≠0

10a/10=130/10

divide by 10 both sides of an equation.

10a/10=130/10

simplify.

130/10=13

answer: a=13

_____________________________________________

Hope this helps!

Thanks!
