Mathematics
1 answer:
Alex3 years ago

Step-by-step explanation:

We can prove that the triangles are congruent using the SAS method.

It's given that GH and JH are congruent (S)

Angle GHF and Angle IHJ are equal since they are vertically opposite (A)

It's given that FH and HI are congruent (S)

Thus, the triangles are congruent, which implies that the remaining sides are equal.

What is the slope of the line in the graph?<br>4th possible answer is 4/3<br>----<br>بنام<br>​
Delvig [45]

Answer: Second option.

Step-by-step explanation:

The slope of a line can be calculated with this formula:

 m=\frac{y_2-y_1}{x_2-x_1}

Then, you need to choose two points of the line shown in the graph and substitute them into the formula for calculate the slope:

Let's pick the points (-4,4) and (4,-2).

Substituting:

m=\frac{-2-4}{4-(-4)}

Simplifiying,  you get that the slope of the line in the graph is:

m=\frac{-2-4}{4-(-4)}\\\\m=\frac{-6}{4+4}\\\\m=\frac{-6}{8}\\\\m=-\frac{3}{4}

Find the area of the rectangle with a length of (x^2-2) and a width of (2x^2-x+2)
Katyanochek1 [597]
Area=legnth times width

so multiply them together use distributive property
a(b+c)=ab+ac so
in this problem
(a+b)(c+d+e)=(a+b)(c)+(a+b)(d)+(a+b)(e)

so
x^2-2 times (2x^2-x+2)=(x^2)(2x^2-x+2)-(2)(2x^2-x+2)=(2x^4-x^3+2x^2)-(4x^2-2x+4)
add like terms
2x^4-x^3+(2x^2-4x^2)-2x+4
2x^4-x^3-2x^2-2x+4

How too solve (2x-3y)(4x-y) by multiplying polynomials by polynomials
Alex777 [14]
(2x-3y) (4x-y)
Multiply the polynomials using distributive property.
(a+b)(c+d) = ac+ad + bc + bd
(2x-3y) (4x-y) = (2x) (4x) + (2x)(-y) + (-3y)(4x) + (-3y)(-y)
Apply plus/minus rule.
-(-a)=a and -(a)=-a
we get
=8x²-2xy-12xy+3y²
Add like terms
=8x²-14xy+3y²

Answer: 8x² - 14xy + 3y²

One maid can clean the house four times faster than another. Working together they can clean the entire house in 4 hours. How lo
stich3 [128]

<u>5 hours</u><u> long would it take the </u><u>faster </u><u>maid cleaning alone.</u>

What is a linear equation in math?

  • A linear equation only has one or two variables.
  • No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction.
  • When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line.

Suppose, time taken by faster maid be x , hours.

So, time taken by slower maid ,

 x_{2} = 4x_{1}        ( 4 time faster maid )

Now, time taken by both of the  made together is given by ,

( \frac{x_{1}x_{2}  }{x_{1} + x_{2} } )

\frac{x_{1}(4x_{1} ) }{x_{1} + 4x_{1} }  = 4 hours

\frac{4x_{1} }{5}  = 4 hours

x_{1} = 5 hours     which is the time required by faster maid.
