What Is The Answer??

Answers

Answer 1

Answer:   x = -3 + √3     or     x = -3 - √3

Answer 2

Step-by-step explanation:

X²+6x+6

now breaking 6x into 2x and 3x we get ,

X²+3x+2x+6

taking x common and 2 common we get ,

x(x+3)+2(x+3)

taking (x+3) common

(x+3) (x+2)

so comparing with zero to get values of x ,

either

x+3=0

x=-3

or x+2=0

x=-2

Angle
X
70°

Answers

Answer:

The angles x and 70 result up to 180.

Hence, they are supplementary.

Value of x:

x+70 = 180

x = 180-70

x = 110

They are supplementary angles. x=110°.

Which of the sets shown includes the elements of Set Z that are both odd numbers and multiples of 5? (B IS NOT CORRECT)
Z = {−15, −12, −10, 2, 7, 10, 20}


A. {-15}

B {-15, −10, 10, 20}

C. {-15, −10, 7, 10, 20}
D. {−15, −12, −10, 2, 7, 10, 20}

Answers

Answer:

a. {-15}

Step-by-step explanation:

Given set Z = {−15, −12, −10, 2, 7, 10, 20}, the odd numbers here are -15, and 7. If we divide both numbers by 2 respectively, we would always have a remainder. Therefore, they are both off numbers.

Between -15 and 7, which can we say is a multiple of 5? Definitely, it's -15. Because 5*3 = 15. There is no integer we can multiply by 5 that will give us 7.

Therefore, the set {-15} includes element of set Z that is both an odd number and a multiple of 5.

If p represents doubling the dimensions of a rectangle and q represents the area increasing by a factor of 4, which are true? Select two options.


p → q represents the original conditional statement.

~p → ~q represents the inverse of the original conditional statement.

q → p represents the original conditional statement.

~q → ~p represents the converse of the original conditional statement.

p → ~q represents the contrapositive of the original conditional statement.

Answers

Answer:

p → q represents the original conditional statement.

Step-by-step explanation:

In the case when p represents the dimensions that is double of a rectangle while on the other hand the q represent the area i.e. increased by a factor of 4

So this both shows the conditional statement i..e real

where,

P termed as hypothesis

And, q termed as a conclusion

Therefore

Triangle ABC is translated 5 units to the right and 4 units up to create triangle A'B'C'.
What is the measure of B?

Answers

I believe it is 74°. Because translations preserve size

The measure of the angle B is 74 degrees.

What is the angle sum property?

The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.

Triangle ABC is translated 5 units to the right and 4 units up to create triangle A'B'C'.

If triangle ABC is translated 2 units up and 2 units right, that means that all the vertices of the triangle are translated by the same units 2 up and 2 right.

The angle sum property of a triangle;

80 + 26 + B = 180

B = 180 - 106

B = 74

Therefore, the size and shape of the triangle wouldn't change.

The triangle A'B'C' will still have the same size and shape, and all the sides will have the same length.

Hence, the measure of the angle B is 74 degrees.

Tristan and two of his friends purchased tickets to a school play. Tristan paid for all the tickets with a $50.00 bill and received $23.00 in change. If Tristan used a coupon for 25% off, what was the original price for one ticket?

Answers

Answer:

$36

Step-by-step explanation:

Tristan paid $50 for the tickets of the school play and was given $23 as change. The amount Tristan paid for the ticket is given as:

Price for ticket = amount paid - change = $50 - $23 = $27

Price for ticket = $27

Given that the ticket was sold at 25% off. Let x be the original price of the ticket, therefore:

x - 25% of x = $27

x - 0.25x = 27

0.75x = 27

x = 27/ 0.75

x = 36

Therefore the original price of the ticket is $36

Answer:

27.00
