<span>-2(6+s)>-15-2s

First step is to distribute. Multiply -2 by everything inside the parentheses.
-12 - 2s > -15 - 2s

Now add 2s to both sides.
-12 > -15 

Now divide both sides by -1, and remember to switch the sign because you divided by a negative number.
12 < 15

This has infinite solutions. </span>

B) Write down the formula to find the perimeter of a circle.​
rewona [7]

Answer:

C = 2πr

Step-by-step explanation:

We know that, the perimeter of a figure is equal to the sum of all sides.

A circle having no sides.

The perimeter of a circle = The circumference of the circle

The formula for the circumference of the circle is given by :

C = 2πr

Where

r is the radius of the circle

Hence, this is the required solution.

What is the perimeter of the figure
Brums [2.3K]

Answer:

The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle. The perimeter, P, is: P=x+x+y+y.

Given triangle ABC, A=105°, a=10cm, b=7cm, find B,C and c.
Whitepunk [10]

The value of the side c will be 5.56 cm and angle C is 32.49° and angle B is 42.51°.

<h3>What is law of cosine?</h3>

Let there is a triangle ABC such that |AB| = a units, |AC| = b units, and |BC| = c units and the internal angle A is of θ degrees, then we have:

a² + b² – 2ab cos C = c²

Given triangle ABC, A = 105°, a = 10 cm, b = 7 cm.

Then we have

7² + c² – (2 · 7 · c) cos 105° = 10²

c² + 3.62c – 51 = 0

On solving, we have

c = 5.56

Then the angle C will be

10² + 7² – 2 · 7 · 10 · cos C = 5.56²

                149 – 140 cos C = 30.91

                                 cos C = 0.8435

                                        C = 32.49°

We know that

       ∠A + ∠B + ∠C = 180°

105° + ∠B + 32.49° = 180°

                         ∠B = 42.51°

HURRY PLEASE
Delicious77 [7]

Answer:

Infinite solutions

Step-by-step explanation:

2x−7y=12 (1)

−x+3.5y=−6 (2)

(2) x = 3.5y + 6

(1) 2(3.5y+6) - 7y = 12

7y + 12 - 7y = 12

12 = 12 (a true statement)

Since the variable got eliminated and we got a true statement, the system has infinitely many solutions.

One of the solutions:

(6,0)
