Answer: x(x-4)+2(x-4)=0 The answer is

=4

= −2

Step-by-step explanation:

Distribute, Then Cobine the like terms, Then you get your solution

(i would go further into explanation but its kinda hard to explain)

I am not completely sure but it's most likely the last option because congruent means equal and the two trapezoids can't be equal because of the different side lengths.

Answer:

b. no solution

Step-by-step explanation:

y=1/4x-4

y=1/4x-1

This pair of equations has the same slope, meaning that they are parallel lines. Parallel lines never intersect so there is no result of solving this system of equations. Therefore, the correct answer would be b, that this system of equations has no solution.

Answer:

NO solution

Step-by-step explanation:

(4 ^2) - 1

Answer:

12

Step-by-step explanation:

Answer:

12 inches

Step-by-step explanation:

if it's a square you have to multiply 2 of the same numbers

one length is 12 inches because

12 x 12 = 144

Answer:

Step-by-step explanation:

2(4.5 x 5) + 2(5.5 x 5) + 2(4.5 x 5.5)= 45+55+49.5=149.5 square inches

Answer:

1. 0.5,4.5

2. 1.5,2

3. 4,4.5

Step-by-step explanation:

The sun is in the middle of both numbers, and there is a 1 gap, So we make it 1/2. To do that for each problem you add 0.5 for each answer in the middle.

Answer:

15

Step-by-step explanation:

to find it we must do this equation:

(25/5) * 3

5 * 3 = 15

To check :

15/25 = 3/5

Answer:

It's called a Diophantine Equation, and it's sometimes known as the “summing of three cubes”: Find x, y, and z such that x³+y³+z³=k, for each k from 1 to 100. One answer is x = 1, y = -1, and z = 2.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Area is + 111.6 square meters

Formula : A/ 3.14 / 2

111.6 / 3.14 = 35.54

35.54 is the radius so multiply by 2 to get diameter .

35.54 / 2 = 17.77

Hope that’s right:)

Answer: 13

Step-by-step explanation:

Answer:

what the

Step-by-step explanation: .

Answer:

Step-by-step explanation:

y = negative 13 over 10x + 13 is the best choice.  (0, 13) is the y-intercept.  If we begin at (0, 13) and move approximately 10 units to the right, y decreases by 13, so the slope is m = -13/10.

Writing y = negative 13 over 10x + 13   as  y = negative 13 over 10  plus 13 would be clearer.  We must emphasize that the slope is -13/10 and that this should be enclosed in parentheses:  y = (negative 13 over 10)x + 13.

Answer:

120 degrees

Step-by-step explanation:

the are across from each other so they would equal the same

Since all the sides are equal, the altitude is

10 sin60° = 5√3

To see this, draw the rhombus ABCD and drop an altitude from D to AB. Now you have a right triangle with hypotenuse=10 and base angle=60°

Answer:

a) 4x+6

b) 28

Step-by-step explanation:

The perimeter is equal to 1+x+1+x+1+1+1+x+1+x.

Simplifying we have 4x+6.

If we plug in 5.5 for x, we get 4*5.5+6=28

Answer:

a)1/25 b)9/49 c)121/64 d)1/100

Step-by-step explanation:

Just square all the values since the area of a square is a²

Answer:

90

Step-by-step explanation:

It would be the same as Triangle A because they are congruent. Congruent means they're identical or the same.

Answer:

Of the liquid surface fresh water, 87% is contained in lakes, 11% in swamps, and only 2% in rivers.

Step-by-step explanation:

The distribution of water on the Earth’s surface is extremely uneven. Only 3% of water on the surface is fresh; the remaining 97% resides in the ocean. Of freshwater, 69% resides in glaciers, 30% underground, and less than 1% is located in lakes, rivers, and swamps. Looked at another way, only one percent of the water on the Earth’s surface is usable by humans, and 99% of the usable quantity is situated underground.

3% of the earth's water is fresh. 2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost. 0.5% of the earth's water is available fresh water.11

Rain and seasonal flooding cause water levels to fluctuate. In the wet soil, water-tolerant vegetation grows and helps maintain a moist, swampy condition. In many freshwater swamps in the southeastern United States, cypress and tupelo trees grow. ... Alligators, frogs, and many other animals live in these swamps.

The large cube is representing: 16*16*32= 8192cm

And the small cube is representing: 16*6*2= 72cm

length(cm) × width(cm) × height(cm) = cubic centimeters(cm³)

&

length(mm) × width(mm) × height(mm) ÷ 1000 = cubic centimeters(cm³)

So, answer would be 2,712.
