Step-by-step explanation:

step 1. ABCD is an isosceles trapezoid because AD and BC are parallel, AB and CD are congruent

step 2. x = 56° (definition of an isosceles trapezoid)

step 3. x + y + z + 56 = 360 (definition of a quadrilateral)

step 4. y = z (definition of an isosceles trapezoid)

step 5. 56 + 2y + 56 = 360

step 6. 2y = 248

step 7. y = 124°, z = 124°.

Answer:

Possible Outcomes = {January , February, March, April,May, June, July, August, September , October , November ,December}

Explanation:

In probability The possible outcomes is a possible result of an experiment which we are performing. Each possible outcome is unique for a particular experiment

Now in this problem we are performing the experiment of putting the names of months in bag

Total months are 12

which are January , February, March, April,May, June, July, August, September , October , November and December

Now

Possible Outcomes = {January , February, March, April,May, June, July, August, September , October , November ,December}

So these are the possible results which can occur in our experiment that which ever we will pick the answer will be one of these 12 names

______

Answer:

____________________

Step-by-step explanation:

Just solve the equation 5-√x = 3

So, let’s solve it:

5-√x = 3 ⇔ 5-3=√x ⇔ √x = 2 ⇔ x=4

Then ?=4

give the standard form, degree, leading coefficient and the constant term of the function h(x) = (2x+1)² (2x-3)

Softa [21]

Answer:

The standard form is: $h(x) = 8x^3 - 4x^2 - 10x - 3$

The function is of the 3rd degree.

The leading coefficient is 8.

The constant term is -3.

Step-by-step explanation:

Placing in standard form:

To place in standard form, we solve the operations. So

$h(x) = (2x+1)^2(2x-3)$

$h(x) = (4x^2 + 4x + 1)(2x - 3)$

$h(x) = 8x^3 - 12x^2 + 8x^2 - 12x + 2x - 3$

$h(x) = 8x^3 - 4x^2 - 10x - 3$

Degree:

The degree is given by the highest power of x, which, in this exercise, is 3.

Leading coefficient:

The leading coefficient is the term that multiplies the highest power of x. In this exercise, the higher power of x is $x^3$ , which is multiplied by 8. So the leading coefficient is 8.

Constant term:

The constant term is the one which does not multiply a power of x. So in this exercise, it is -3.

If you add Natalie's age and Fred's age, the result is 46. If you add Fred's age to 4 times Natalie's age, the result is 91.

Ivenika [448]

Answer:

Fred = 31

Natalie = 15

Step-by-step explanation:

We have Natalie and Fred's whos age are unknown, we know that when added, their ages equal 46. While when multiplied with Natalie's age 4 times, their ages is 91.

Create two systems :

F = Fred

N = Natalie

F + N = 46

4N + F = 91

We can change the first equation to Natalie's age alone :

N = 46 - F

Now substitute this into the second equation :

4(46 - F) + F = 91

Distribute :

184 - 4F + F = 91

Subtract 184 from both sides :

-4F + F = -93

Add like terms :

-3F = -93

Divide -3 from both sides :

F = 31

Therefore, Fred is 31 years old. Now replace his age in the first equation :

31 + N = 46

46 - 31

Therefore, Natalie is 15 years old.
