Answer:

Step-by-step explanation:

Factor the numerators/ denominators

10 - 5 = 5(2a - 1) ← common factor of 5

4a² - 1 = (2a - 1)(2a + 1) ← difference of squares

[ Change ÷ to × and turn second fraction upside down ]

= $\frac{2a+1}{5(2a-1)}$ × $\frac{(2a-1)(2a+1)}{10a}$

[ cancel the factor (2a - 1) on the numerator/denominator ] leaving

= $\frac{(2a+1)^2}{5(10a)}$ = $\frac{(2a+1)^2}{50a}$

Answer:

<DEB= 125 degrees

Step-by-step explanation:

To get this, you would need to know all 2 angles of the triangle.

To find the first angle, simply do 180-107 to get 73(because supplementary angles add up to 180 degrees).

Next, 180-52(given angle)-73 to get 55 because the 3 angles of a triangle add up to 180(triangle angle sum theory).

You would see that <DEB is part of another supplementary angle so, do 180-55 to get 125.

<DEB=125 degrees.

i figure is formed by a square and a triangle. total area is 32.5 m. the area of the triangle is 75 m. what is the length of eac

Anni [7]

Answer:

The length of each side of the square is 5 meters

Step-by-step explanation:

<u><em>The correct question is</em></u>

A figure is formed by a square and a triangle. total area is 32.5 m^2. the area of the triangle is 7.5 m^2. what is the length of each side of the square?

we know that

The total area of the figure is equal to the area of triangle plus the area of square

The area of square is equal to the area f the figure minus the area of triangle

Let

A ----area of the square

$A=32.5-7.5=25\ m^2$

Find the length side of the square

Remember that the area of the square is

$A=b^2$

where

b is the length side of the square

substitute

$25=b^2$

square root both sides

$b=5\ m$

therefore

The length of each side of the square is 5 meters

Edge of a cube is one side length
One side is a^2 so then you would cube that to get the volume of the cube
a^2×a^2×a^2 = a^6
D. a^6
