Find the value of x.
Answer:
10
Step-by-step explanation:
since it is a right angle triangle
[tex] {x}^{2} = ({5 \sqrt{2} })^{2} +({5 \sqrt{2} })^{2} [/tex]
[tex] x = \sqrt[2]{(5 \sqrt{2} )^{2} +( 5 \sqrt{2})^{2}} [/tex]
[tex]x = \sqrt{(25 \times 2) + (25 \times 2)} [/tex]
[tex]x = \sqrt{50 + 50} [/tex]
[tex]x = \sqrt{100} [/tex]
[tex]x = 10[/tex]

The system has how many solutions?
Answer:
two solutions ldk because thethe lines are split into four and if you take away two you still have four more I really don't know this
Answer:
No solution.
Step-by-step explanation:
[tex]y = 2x + 3 \\ y = 2x - 1[/tex]
Both equations are in slope-intercept form so we can combine both equations.
[tex]2x + 3 = 2x - 1[/tex]
Solve the equation.
[tex]2x - 2x = - 1 - 3 \\ 0 = - 4[/tex]
Both sides are different. Therefore, both graphs are parallel and no solutions.
For what values of x and y are the triangles to
the right congruent by HL?
Answer:
x = 6
y = 2
Step-by-step explanation:
For both triangles to be congruent, their hypotenuse lengths and the corresponding length of the other leg must be equal to each other.
Thus:
x = y + 4 ---› Eqn. 1
x + 2 = 4y ----› Eqn. 2
Substitute x = (y + 4) into equation 2.
(y + 4) + 2 = 4y
y + 4 + 2 = 4y
y + 6 = 4y
y - 4y = -6
-3y = -6
y = 2
Substitute y = 2 into equation 1
x = y + 4 ---› eqn. 1
x = 2 + 4
x = 6

Answer:
7 squares
Step-by-step explanation:
Key skills: Counting, Averages
1) Based on what I counted, there are 11 columns, and 53 squares. If you want an average of 5 squares per column and you have 12 columns, the total number of squares you want is 60.
2) Since there are already 53 squares present, you need 60-53 = 7 squares more.
Hope you understood and have a nice day!!
answer:
should be 7 squares.
create a table and graph y=x+1 demos
Answer:
The table will be:
x y=x+1
1 2
2 3
3 4
4 5
5 6
The graph is shown in figure attached.
Step-by-step explanation:
We need to create table and graph the expression: [tex]y=x+1[/tex]
Table is made, such that we take value of x and find value of y
You can take any values of x from negative values to positive values. I am taking values of x: 1,2,3,4,5 and find value of y.
So our table will be:
x y=x+1
1 2
2 3
3 4
4 5
5 6
Now, we will plot these value on the graph. x values will be on x-axis and corresponding y-values will be on y-axis.
The graph is shown in figure attached.

9. What is 3/8x3/8x3/8 written as a power?
Answer:
3^3/8^3
Step-by-step explanation:
because since there are 3 three's in 3/8, it will have to be 3^3 and since there are 8 three's, it will be 8^3. so the answer will be 3^3/8^3
The representation of the expression (3/8)x.(3/8)x.(3/8)x in terms of power is [(3/8)x]³.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Find the unknown side length of the rectangle if its area is 11m 2.
3 m
?
11 m
Answer:
the side length is 3.
Step-by-step explanation:
you would do 11/3 2/3
and you would get 3
The area of a shape is the amount of space it occupies
The width of the rectangle is 3 meters
The length of the rectangle is given as:
[tex]Length = 3\frac 23[/tex]
The area of the rectangle is given as:
Area = 11m^2
The area of the rectangle is calculated using:
[tex]Area = Length * Width[/tex]
So, we have:
[tex]11 = 3\frac 23* Width[/tex]
Express mixed number, as an improper fraction
[tex]11 = \frac {11}3* Width[/tex]
Multiply both sides by 3
[tex]33 = 11* Width[/tex]
Divide both sides by 11
[tex]3 = Width[/tex]
Rewrite as:
[tex]Width = 3[/tex]
Hence, the width of the rectangle is 3 meters

4(x-7)=2(x+3) solve for x
Answer:
x=17.... I checked on mathaway and did it myself should be correct
Answer:
x=17
Step-by-step explanation:
2(x-7)=(x+3) divide both sides by two
2x-14 =(x+3) distribute
2x-14-x-3=0 substract x+3
x-17=0 combine like terms
x=17 add 17 to both sides

Find the perimeter and area of the rectangle.
6.9 in
2.4 in
Answer:The perimeter = 18.6 , The area= 16.56
Step-by-step explanation: The perimeter is all sides added together and there are four sides and two sides are even , so there are two ways to find it. {1} 6.9x2=13.8 , 2.4x2=4.8; 13.8+4.8=18.6…{2} 6.9+6.9+2.4+2.4=18.6.
The area is two sides multiplied together so, 6.9x2.4=16.56
