WILL GIVE BRAINLIST!!!!!!!FACTOR THIS COMPLETELY 4x^2 − 25

Mathematics
1 answer:
Wittaler [7]3 years ago

Answer:

(2x - 5)(2x +5)

Step-by-step explanation:

4x^2 is a perfect square with a square root of 2x, and 25 is also a perfect square with a square root of 5. The difference of two perfect squares a and b can be written as (\sqrt{a} - \sqrt{b} )(\sqrt{a} +\sqrt{b} ). So, 4x^2 - 25 can be factored into (2x-5)(2x+5).

Hope that helped! ;)

Can somebody help me first answer gets brainiest pls help

Answer: I believe the answer is 216 Square units.

Explanation:
1. Cut the shape in half. Now you have a square and a triangular shape.

2. The square is 12 inches on all four sides. 12 • 12 = 144. 144 is the area for the square.

3. Now, the triangular shape. The bottom of the shape is 12 because we divided the total 24 in half with the square. The left side (the longer side) of the shape is also 12 because it is parallel to the square with 12 as the same measurement. The right side (the shorter side) of the shape is 6 because it's half the size of the square’s length. The length of the top of the shape is also 12 because it is half of the square’s width of 24.

4. Now that we have found the measurements of the triangular shape, we can multiply (length • width) and add. The square is 144 units (12•12=144) and the triangular shape is 72 (12•6=72). 144 + 72= 216.

I hope this helps! :)

Answer:

\textsf{(a)} \quad (3x)^{\circ}+(x+14)^{\circ}=90^{\circ}

\textsf{(b)} \quad m \angle 1=\boxed{57}\:^{\circ}

       m \angle 2=\boxed{33}\:^{\circ}

Step-by-step explanation:

From inspection of the given diagram:

  • m \angle 1=(3x)^{\circ}
  • m \angle 2=(x+14)^{\circ}

<h3><u>Part (a)</u></h3>

A right angle is 90° and is represented by the ∟ symbol.

To find x, <u>equal</u> the sum of the angles to 90° and solve for x:

\implies m \angle 1+m\angle2=90^{\circ}

\implies (3x)^{\circ}+(x+14)^{\circ}=90^{\circ}

\implies 3x+x+14=90

\implies 4x+14=90

\implies 4x+14-14=90-14

\implies 4x=76

\implies 4x \div 4=76 \div 4

\implies x=19

<h3><u>Part (b)</u></h3>

To find the degree measure of each angle, substitute the found value of x into the expression for each angle.

\implies m \angle 1=(3 \cdot 19)^{\circ}=57^{\circ}

\implies m \angle 2=(19+14)^{\circ}=33^{\circ}
