How do I expand this? 3(2y-5)

Answers

Answer 1

Answer:

Answer:

Given the expression $3 (2y-5)$ ......[1]

Distributive property of multiplication states that when a number is multiplied by the sum of two numbers, then the first number can be distributed to both of those numbers and multiplied by each of them separately. i.e,

$a \cdot (b+c) =a\cdot b +a \cdot c$

then, by using distributive property in equation [1]

$3(2y-5) = 3 \cdot 2y - 3\cdot 5$

= $6y-15$

Therefore, the expanded form of 3(2y-5) is; 6y-15

Answer 2

Answer: $3\cdot(2y-5)=3\cdot2y-3\cdot5=6y-15$

what's supposed to be in the space?

Answers

so first you simplify
24+x=120/3
120/3=40
24+x=40
subtract 24 from both sides
x=16

120/3= 40
40-24=16

16 is in the blank space

Which statement accurately describes how adding a number, n, to the function f(x)=sin(x) affects its graph?A. There is a vertical shift of n units.
B.The x-intercepts will shift n units.
C. There is a change in amplitude of n units.
D. The range will change by a factor of 2n units.

Answers

The correct answer is:

A) There is a vertical shift of n units.

Explanation:

When a parent function is transformed, each type of transformation results ina different change in the graph.

The parent function in this question is f(x) = sin(x).

Adding n units to the end of this function would result in f(x) = sin(x) + n.

When a function is transformed by adding a constant to the end of a function results in a vertical shift by that number of units. In this case, it would be a vertical shift n units.

The sum of interior angle of a regular polygon is 1980 . Find its angle .

Answers

The sum of the angles of any polygon with 'n' sides is (n - 2) times 180 degrees.

1980 / 180 = 11 , so the polygon has 13 sides and 13 angles.

If the polygon is regular, then all the angles are equal.

Each interior angle is 1980/13 = 152.308 degrees (rounded)
