A triangle has squares on its three sides as shown below. What is the value of x? Three squares having side lengths 3 cm, x cm,

Pani-rosa [81]

Answer:

The value of x is 5 centimeters.

Therefore, option 3 is correct.

Step-by-step explanation:

A triangle has three sides 3,x and 4 cms

Since the triangle is right angle triangle so, it will follow the Pythagoras theorem:

$hypotenuse^2=side^2+side^2$ (1)

We have been given three sides x,3 and 4

On substituting the values in (1) we get:

$x^2=3^2+4^2$

$x^2=9+25$

$\Rightarrow x=5$

Hence, the value of x is 5 centimeters.

Therefore, option 3 is correct.

Please look at the attachment for the figure.

What is the value of x

VLD [36.1K]

Answer:

value of x = 8

Step-by-step explanation:

if the given lines are parallel, then the shown pair of angles are corresponding angles,

and we know that the the pair of corresponding angles are equal so,

=》16x - 8 = 120

=》16x = 128

=》x = 128 ÷ 16

=》x = 8

The length and breath of a rectangle are (a^2 +ab +b^2) units and (a-b) units.Find the area of the rectangle.

pshichka [43]

Answer:

a^3 - b^3.

Step-by-step explanation:

Area = length * breadth

= (a - b)(a^2 + ab + b^2)

= a(a^2 + ab + b^2) - b(a^2 + ab + b^2)

= a^3 + a^2b + ab^2 - a^2b - ab^2 - b^3

Note: the 4 middle terms cancel out. So the answer is

a^3 - b^3.

Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2, and the profit

Volgvan

Answer:

See below

Step-by-step explanation:

Given equation:

2x + 3y = 1470

Change to slope-intercept form:

2x + 3y = 1470, isolate y
3y = -2x + 1470, divide all terms by 3
y = -2/3x + 490

The slope is -2/3 and y-intercept is 490

Functional notation, change y to f(x)

f(x) = -2/3x + 490

To graph the line, plot the intercepts and connect with the line.

If the total is $1593 for the next month, the function would be:

2x + 3y = 1593

Changing to slope-intercept:

y = -2/3x + 531

The slopes are same, therefore the lines are parallel.

The difference is the y-intercept, it is greater in the next month.

The graphs are attached, with intercepts shown.
