Subtract:-8y+2y^2-37 Explanation: you will start off by simplifying each term so you would raise 5 to the power of 2 and get -1x25-9y-4-(-2y2-y+8) and you then multiply -1 by 25 so you would do -25-9y-4-(-2y^2-y+8) and then you would apply distributive property so you would do -25-9y-4+(2y^2)- -y-1x8 and then you simplify and get -25-9y-4+2y^2+y-8 and lastly you would simplify by adding terms so you would subtract 4 from -25 so do −9y-29+2y^2+y-8. And then add -9y and y by doing -8y-29+2y^2-8 and subtract 8 from 29 and get your answer as -8y+2y^2-37

Find angles A, B, C, D, & E.
matrenka [14]

Answer:

Step-by-step explanation:

B = 35      {Alternate interior angles}

C = 75      {Corresponding angles}

D + 75 =  180 {Linear pair}

     D = 180 - 75

     D = 105

A = C   {Corresponding angles}

A = 75

E = A   {Alternate interior angles}

E = 75

Anyone that can help me with this please?Not soo good at math.​
kakasveta [241]

As it is right angled , we can use pythagoras theorem.

Using the therorem :

(x+2)² + (4x+4)² = (5x)²

x² + 4x + 4 + 16x² + 32x + 16 = 25x²

25x² - 17x² - 36x - 20 = 0

8x² - 36x - 20 = 0

2x² - 9x - 5 = 0

2x² -10x + x - 5 =0

2x(x-5) + 1(x-5) =0

(x-5)(2x+1) = 0

x = 5 or x = -1/2

x cannot be -1/2 as it would make hypotenuse negative.

So x = 5

Sides are 7 m, 24 m , 25 m

The area = 1/2 × base × height

Area = 1/2 × 24 × 7 = 84 m²
