Answer:

(B) {\angle}4 and {\angle}7 are congruent corresponding angles and  {\angle}7 and {\angle}6 are vertical angles.

Step-by-step explanation:

It is given that line m is parallel to line n.

Now, {\angle}4 is congruent to {\angle}7 because they are corresponding angles which are always congruent.

Also, {\angle}7 is congruent to {\angle}6, because they form vertically opposite angle pair, thus

{\angle}4 will be congruent to {\angle}6.

Hence, Cruz is correct that {\angle}4 is congruent to {\angle}6 because {\angle}4 and {\angle}7 are congruent corresponding angles and  {\angle}7 and {\angle}6 are vertical angles.

Therefore, option B is correct.

Answer:

It could fly 10,8 kilometers.

Step-by-step explanation:

The European swallow fly speed is 12 meters per second.

We have to calculate how many kilometers it could fly in 15 minutes.

This can be calculated using the equivalent factors for each of the units:

- 1 km is equivalent to 1,000 meters.

- 1 minute is equivalent to 60 seconds.

We know that the distance travelled by the fly is the product of the speed and the time, so we have:

D=v\cdot t\\\\\\D=12\,\dfrac{m}{s}\cdot15\, min\\\\\\D=12\,\dfrac{m}{s}\cdot(\dfrac{1\,km}{1,000\,m})\cdot15\, min\cdot (\dfrac{60\,s}{1\,min})\\\\\\D=\dfrac{12\cdot 15\cdot 60}{1,000}\,km=\dfrac{10,800}{1,000}\,km\\\\\\D=10,8 \,km

Solve the following equation using algebric formulas<br> (x-y)(x+y)
photoshop1234 [79]

The simplified expression of (x + y)(x - y) is x^2 - y^2

<h3>How to solve the expression?</h3>

The expression is given as:

(x + y)(x - y)

Expand the bracket

x(x - y) + y(x -y)

Further, expand

x^2 - xy + xy - y^2

Evaluate the like terms

x^2 - y^2

Hence, the simplified expression of (x + y)(x - y) is x^2 - y^2

Hello, can someone help me with the working out to this problem
timama [110]

\text{If}~ \alpha ~\text{and}~ \beta~ \text{are the roots,}\\ \\x^2 -(\alpha + \beta)x +\alpha\beta = 0\\\\\text{For}~ x^2+3x-2=0\\\\\alpha +\beta=-\dfrac ba=-3\\ \\\alpha \beta = \dfrac ca = -2\\\\

\text{So,~} \alpha^3+\beta^3 = (\alpha + \beta)(\alpha^2 + \beta^2 -\alpha \beta)\\ \\~~~~~~~~~~~~~~~~=(\alpha+\beta)\left[(\alpha +\beta)^2 -2\alpha \beta - \alpha \beta\right]\\\\~~~~~~~~~~~~~~~~=(\alpha+\beta)\left[(\alpha +\beta)^2 -3\alpha \beta \right]\\\\~~~~~~~~~~~~~~~~=-3\left[(-3)^2-3(-2)\right]\\\\~~~~~~~~~~~~~~~~=-3(15)\\\\~~~~~~~~~~~~~~~~=-45\\\\\text{And}~~~\alpha^3 \beta^3= (\alpha \beta )^3 = (-2)^3 = -8\\\\

\text{Hence the equation whose  roots are}~ \alpha^3 ~\text{and}~ \beta^3~ \text{is:}\\ \\ x^2-(\alpha^3 + \beta^3)x +\alpha^3 \beta^3 =0\\\\\implies  x^2 -(-45)x+(-8)=0\\\\\implies x^2 +45x -8=0

Root of 108 is between______ and ______
natita [175]
Without using a calculator I would say the root is between 10 and 11 

How I found the answer:
I know 10 * 10 = 100
I know 11 * 11 = 121
So the root of 100 = 10 and the root of 121 = 11 so that means the root of 108 is somewhere between 10 and 11, which the root of 108 =  10.3923

Answer:

n = -1.25

Step-by-step explanation:

S(ABCD) = AB × AD

S(ABCD) = 2n × (4n + 5)

S(ABCD) = CD × AD

2n × (4n + 5) = CD × (4n + 5)

n = -1.25
