Answer:

Z = 3

Step-by-step explanation:

if y = 3 then 3 x 2 = 6 subtract that from 9 and u get 3 so therefore z is 3

Answer:

a) pentagon

b) concave

c) not regular

Step-by-step explanation:

a) this polygon has 5 sides, known as a pentagon

b) it is concave because you can connect the top two vertices with a diagonal which will be outside the shape

c) a regular polygon is equilateral (all sides equal) but the markings show that is not the case with this shape

Answer:

x = 2

Step-by-step explanation:

Given the equation as;

log 3 + log x - log(x + 1) = log 2

collect like terms

log x - log(x + 1) = log 2-1og 3

Re-write the equation by applying laws of logarithms in that when you subtract logs you divide the numbers/terms. This will give

log [ x / x+1 ] = log [2/3]

Cancel log on both sides to remain with;

x/ x+1 = 2/3

Apply cross-product

3{x} = 2{x+1}

3x = 2x + 2

3x-2x = 2

x = 2

Please check the explanation.

Step-by-step explanation:

Given the statement:

''Twice the difference of a number and 2 is added to 6 and the result is 4 more than 3 times the number''.

Let us break down the statement into an algebraic expression.

First Portion:

Let the number be: n

The difference of a number n and 2: n -2

Twice the difference of a number n and 2: 2(n-2)

Twice the difference of a number and 2 is added to 6 = 2(n-2) + 6

Second Portion:

3 times the number n:  3n

4 more than 3 times the number: 3n + 4

Combine the First portion and Second Portion:

Twice the difference of a number and 2 is added to 6 and the result is 4 more than 3 times the number:

2(n - 2) + 6 = 3n + 4

Therefore, the required algebraic expression is:

BONUS SOLUTION to determine the number n

Let us solve the expression

2(n - 2) + 6 = 3n + 4

2n - 4 + 6 = 3n + 4

flip the equation

3n + 4 = 2n - 4 + 6

3n + 4 = 2n + 2

3n - 2n = 2 - 4

n = -2

Thus, the value of n = -2

as an instinct i thought that i should multiply 11 and 5, so im saying 55 different selections

Step-by-step explanation:

sorry if im wrong

Answer:

I believe the answer is 4. Please correct me if I’m wrong.

Step-by-step explanation:

================================================

Work Shown:

A = old velocity = 2 m/s

B = new velocity = 10 m/s

C = change in time = 5 seconds

D = average acceleration

D = (change in velocity)/(change in time)

D = (B-A)/C

D = (10-2)/5

D = 8/5

D = 1.6 m/s^2

The acceleration 1.6 m/s^2 means that the velocity is increasing by 1.6 m/s for every second.

Step-by-step explanation:

70 x 10 = 700

Answer: n = -56

Step-by-step explanation:

first, we multiply both sides by 7, un order to get the variable by itself. this is the important step.

-56 = n

then, we just simply swap the sides in order to get the variable on the left. (not necessary, just looks like a proper equation that way.)

n = -56

work:

-8 = n/7

x7    x7

-56 = n

n = -56

If two sides and a angle are given, then this can be used to find a second angle. With being given the measurements of two sides and an angle, this could result in one or two triangles. Johannes von Muller was the one who was discovered the Law of Sines

Answer:

(16,60)

Step-by-step explanation:

Answer:

Both of the angles are 45°.

Step-by-step explanation:

Because the both have the mark that proves their congruency, and there is a right angle, the need for the entire triangle to be 180° would be to add another 90°. 90/2=45, so both of those angles are 45°.
