Answer:
square the whole equation
Step-by-step explanation:
so, it will change from (3x + 7y)² to 9x² - 49y²
I hope this helps a little bit.
Answer:
(3x - 7y)
Step-by-step explanation:
we know that
.. (a + b) (a - b) = (a^2 - b^2)
=> (a + b) = (3x + 7y)
=>. (a^2 - b^2) = (9x^2 - 49y^2)
=> so, (a - b).= (3x - 7y)

maths angles- please help asap
Answer:
x = 20
Step-by-step explanation:
These angles are same-side supplementary, therefore they add up to 180°.
[tex]4x + 5x = 180 \\ 9x = 180 \\ x = 20[/tex]
Answer:
4x + 5x = 180
because of interior angle
hence, 9x = 180
x = 180/9
x = 20
one angle = 20*4 = 80
another angle = 20*5 = 100
hope it helps
what is m<M to the nearest degree? show your work.
Answer:
27°
Step-by-step explanation:
We solve the above question using the Trigonometric function of Sine
sin theta = opposite/Hypotenuse
Opposite = 5
Hypotenuse =11
sin theta = 5/11
theta = arc sin (5/11)
theta = 27.035691789°
Approximately = 27°
Angle m<M = 27°

?] cm2
lateral surface area of this cylinder is 1584/7 or 226.28...cm square.
The lateral area of the cylinder is 226.2 cm² .
What is lateral surface area of cylinder?The lateral surface of an object is all of the sides of the object, excluding its base and top. The lateral surface area is the area of the lateral surface.
For a right circular cylinder of radius r and height h, the lateral area is the area of the side surface of the cylinder:
A = 2πrh.
According to the question
radius of cylinder = 3 cm
height of cylinder = 12 cm
The lateral area of the cylinder:
A = 2πrh
A = 2 * [tex]\frac{22}{7}[/tex] * 3 * 12
A = 226.2 cm²
Hence, the lateral area of the cylinder is 226.2 cm² .
