Step-by-step explanation:

Difference of squares: A² - B² = (A + B)(A - B).

Therefore 49x² - 16 = (7x)² - (4)² = (7x + 4)(7x - 4).

The correct answer is Option B.

Answer:

y=0/0

Step-by-step explanation:

Step 1: Add -y to both sides.

y+z+−y=y+z+−y

z=z

Step 2: Add -z to both sides.

z+−z=z+−z

0=0

Step 3: Divide both sides by 0.

0/0=0/0

y=0/0

Answer:

y=-1

Step-by-step explanation:

the y line is the up down (vertical) line x is left right (horizontal) line

y=-1 means that the y value will always be over the -1 point on the x line

Answer:

x= -1

Step-by-step explanation:

just by looking at the graph you can see that the equation will be true when x is equal to negative 1

the slope here is undefined and there is no y-intercept, which is why the equation is just x=-1

Answer:

The value of x is 4

Step-by-step explanation:

From what we can see in the diagram , the bigger triangle has lengths that are twice the smaller one

Thus, mathematically;

2(3x-4) = 16

3x - 4 = 8

3x = 8 + 4

3x = 12

x = 12/3

x = 4

Answer:

In California, we need more rain to sustain the health of our natural environment, argriculture, and economic. A group of statistics students in Oxnard College recorded the amount of rain during 2016-2017 school year, measuring the intensity by the inches of rain, and the results were:

Inches of Rain 1 2 3 4 5 6

Frequency 2 4 3 3 7 3

The mean (¯xx¯) rain intensity: ____ inches (Please show your answer to 1 decimal place.)

The median rain intensity: __3.8__ inches

Step-by-step explanation:

the answer is 3.8

Answer:

2.63 inches

3 inches

2, 3 inches

Step-by-step explanation:

The mean of the data is

[tex]\dfrac{1\times 4+2\times 5+3\times5+4\times4+5\times1+6\times0}{4+5+5+4+1+0}=2.63[/tex]

The mean rainfall is 2.63 inches.

The sum of the frequency is [tex]4+5+5+4+1+0=19[/tex]

which is odd so the median is at the

[tex]\dfrac{19+1}{2}=10[/tex] position

The cumulative frequency at 3 inches is 14.

So, the median is 3 inches of rain.

The mode will be 2, 3 inches of rain as they have the highest frequency.

12 shelves

Step-by-step explanation:

playstation games = 48

xbox games = 36

Each shelf will have the same number of playstation and xbox games.

Find the common multiples of 48 and 36

48 = 2, 3, 4, 6, 8, 12, 16, 24, 48

36 = 2, 3, 4, 6, 9, 12, 18, 36

The common multiples are 2, 3, 4, 6, and 12

Therefore, the possible number of shelves Joe will use is

2 shelves

Answer:

  20.9 inches

Step-by-step explanation:

The perimeter length is the sum of the lengths of the two straight edges and that of the curved edge.

  P = r + r + rα . . . . . where α is the central angle in radians

35° is (35°/180°)π radians, about 0.6109 radians

Then the perimeter is ...

 P = r(2 +α) = (8 in)(2 +0.6109) ≈ 20.9 in

The perimeter of the slice is about 20.9 inches.

Answer:

it's answer is 3.75

Step-by-step explanation:

Hypotenuse (h) = 6.25

Perpendicular (p) = 5

base (b) = ?

By using Pythagoras theorem we get

b = √ ( h² - p²)

= √( 6.25)² - 5²

= √ 14.0625

= √(3.75)²

= 3.75

A=5.8

A=b×h/2

If area of the triangle  is 5.8 square meters then the length of the base is 4 meters.

A triangle is a three-sided polygon that consists of three edges and three vertices.

Area of the given triangle is five point eight square meters.

The height of the triangle is two point nine meter (2.9 m).

We need to find the length of the base.

Area of triangle =1/2×Base×Height

5.8 = 1/2 ×Base × 2.9

5.8=1.45 Base

Divide both sides by 1.45

Base = 5.8/1.45

Base = 4 meters

Hence, if area of the triangle  is 5.8 square meters then the length of the base is 4 meters.
