Answer:

(B)

Step-by-step explanation:

Consider a trapezoid whose bases are 6 and 10 and the height is 4, then the area of the trapezoid is given as:

Area=(\frac{b_{1}+b_{2}}{2})h

Area=(\frac{6+10}{2})(4)

Area=16{\times}2

Area=32 sq units

Therefore, the area of the trapezoid is 32 sq units.

I don’t know how to necessarily complete the tables but i know they are equivalent

1. 3(x-5)
3 (x) = 3x
3 (-5) = -15

that is the distributive property thus it equals

3x - 15

2. 3x - 15

they’re the same

tres cajas contienen cuatrocientas naranjas la primera tiene veinte naranjas mas q la segunda y treinta mas q la tercera cuantas
Lemur [1.5K]

Answer: Box3 has 120 oranges.

Box1 has 150 oranges.

Box  has 130 oranges.

Step-by-step explanation:

I will answer this in English.

The question says:

3 boxes have 400 oranges.

The first one has 20 more than the second and 30 more than the third.

So we have 3 equations:

box1 + box2 + box3 = 400

box1 = box2 + 20

box1 = box3 + 30

Now, we can take the variable box1 in the third equation and replace it on the other two.

box3 + 30 + box2 + box3 = 400

box3 + 30 = box2 + 20

Now we can isolate one of the variables in the second equation, let's isolate box2.

box2 = box3 + 30 - 20 = box3 + 10

now we can replace it in the other equation:

box3 + 30 + box2 + box3 = 400

box3 + 30 + box3 + 10 + box3 = 400

3*box3 + 40 = 400

3*box3 = 400 - 40 = 360

box3 = 360/3 = 120.

Box3 has 120 oranges.

Box1 has 120 + 30 = 150 oranges.

Box  has 150 - 20 = 130 oranges.

Which of the following shows the equation after both sides have been distributed correctly -4(x-2)=5(3x-8)?
salantis [7]
The answer is the second option, -4x-8=15x-40

When you distribute the first thing you do is kcf, which means keep change flip. Then you distribute.

I hope I’m correct if I’m not please let me know

Suppose the heights of the members of a population follow a normal distribution. If the mean height of the population is 68 inch
Irina18 [472]

The empirical rule states that at 95% the measurements would be within 2 standard deviations of the mean.


You are given a mean of 68 inches and a standard deviation of 4.

2 times the standard deviation = 2 x 4 = 8

So 95% of the heights would be between 68-8 = 60 inches and 68+8 = 76 inches.
