Yes you are correct. this is due to the distributive property of multiplication.
a(b+c)=ab+ac
so -1(2x+10)=-1(2x)+(-1)(10)
=-2x-10

Yes, that is correct due to the distributive property. It states that you can distribute a number to another number.
for example: a(b + c) = ab + ac
in this case, you are distributing the -1 into the 2x + 10
-1(2x + 10)
(-1) * (2x) + (-1) * (10)
(-2x) + (-10)
-2x - 10

The area of the circle above is 1,519.76 units squared. what is the circumference
murzikaleks [220]
In order to find the circumference, we first need to find the radius.  We have the area, so we can find the radius.  We set up this equation:

1519.76= \pi  r^{2}

We begin by dividing both sides by pi.

483.76 = r^{2}

Next, we take the square root of both sides to get the radius.

r = 22.

Next, we plug this into the formula for the circumference, 2 pi r

C = 2 \pi *22=138.23

So, the circumference of this circle is 138.23 units.

Use the image below to answer the following question. Find the value of sin x® and cos yº What relationship do the ratios of sin
Flauer [41]

Answer:

sin(x) and cos(y) are equal and have ratio of 1 : 1

First find the missing hypotenuse using Pythagoras theorem:

a² + b² = c²

12² + 5² = c²

c = √144+25

c = 13

using sine rule:

sin(x) = \dfrac{opposite}{hypotenuse}

sin(x) = \dfrac{5}{13}

using cosine rule:

cos(y) = \dfrac{adjacent}{hypotenuse}

cos(y) = \dfrac{5}{13}

How is the way the decimals point moves when you divide a decimal number by a power of ten the same as when you multiply? how is
Svetach [21]

Multiplying decimals is the same as multiplying whole numbers except for the placement of the decimal point in the answer. When you multiply decimals, the decimal point is placed in the product so that the number of decimal places in the product is the sum of the decimal places in the factors.

HELP PLZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ
kifflom [539]

Answer: x ≥ -4 (in words: x is greater than or equal to -4)

Step-by-step explanation:

The number line shows all values greater than -4 being shaded in, meaning that x can be any of them.  In addition, the point at -4 itself is shaded in, showing that it is also a possible value for x.

A helicopter's rotor sweeps out an area of 121 pi square
Nuetrik [128]

Answer:

<h2>22 meters.</h2>

Step-by-step explanation:

It's important to notice that the area is circular, which is defined by

A= \pi r^{2}

Replacing given values and solving for r, we have

121 \pi = \ pi r^{2} \\121=r^{2}\\ r= \sqrt{121}=11

But, the diameter is twice the radius, so

d=2r=2(11)=22

Therefore, the diameter is 22 meters.
