Answer:

C. -2x-7y

Step-by-step explanation:

We have been given an expression -(4x+y)+2(x-3y). Weare asked to simplify our given expression.

Using distributive property property a(b+c)=ab+ac, we will get:

-1*4x-1*y+2*x-2*3y

-4x-y+2x-6y

Now, we will combine like terms.

-4x+2x-y-6y

-2x-7y

Therefore, the simplified form of our given expression would be -2x-7y and option C is the correct choice.

Figure f is a scaled copy of Figure e.
Mekhanik [1.2K]

The correct equation of the scaled figure is given by 6/3 = 4/a

<h3>Scaling</h3>

Scaling is the process of either increasing or decreasing the size of a figure by a factor.

From the diagram attached, Figure f is a scaled copy of Figure e. Figure e is decreased to produce figure f, hence:

  • AB/XY = CD / WZ
  • 6/4 = 3 / a
  • 6/3 = 4/a

The correct equation of the scaled figure is given by 6/3 = 4/a

What is the length of the missing leg?
sp2606 [1]

Answer:

a=12

Step-by-step explanation:

Pythagorean Theorem: a^{2}+b^{2}=c^{2}

In this case, a = 9, b = a, and c = 15.

9^{2}+a^{2}=15^{2}

81+a^{2}=225

The, we subtract 81 from both sides getting:

a^{2}=144,

Then, a=12

NEED HELP FAST 100 POINTS AND BRAINLIEST
Shtirlitz [24]

Answer:

1)The mass of water increases.

2) Freezing point of water decreases.

3) buoyancy of objects in the water increases.

Step-by-step explanation:

Salinity in the oceanic water is attributed by the water coming from other sources like rivers carrying rocks and soil containing salt. Salinity decreases the temperature of water, making it cold and more denser. The cold water settles at the bottom of the ocean. It flows across the oceanic basins as slow currents. The objects being less in density flows over the surface of water. Hence,buoyancy of objects in water increases.

Anyone know this I need help
horrorfan [7]

Answer:

option D

Step-by-step explanation:

we have a right triangle

we know

c^2=a^2+b^2

c=hypotenuse

c=52 cm

a=48 cm

b= 20 cm

we  substitute in the equation c^2=a^a+b^2

so we have

52^2=48^2+20^2

52= sqrt(48^2+20^2)

52= sqrt(2304+400)

52= sqrt(2704)

52cm=52cm

so c=52 cm

so the option D is the correct answer
