Cubic polynomial

${x}^{3} + {2x}^{2} - 5x - 10$

Binomial

$2x - 3$

By vertical method of multiplication we get,

${2x}^{4} + {x}^{3} - {16x}^{2} - 5x + 30$

What is the solution set of 2x2-3x=5

Kryger [21]

You use the quadratic formula:

2x {}^{2} - 3x = 5

2x {}^{2} - 3x - 5 = 0

x = \frac{3 + - \sqrt{9 -4(2)( - 5)}}{2 \times 2}

x = \frac{3 + - \sqrt{49} }{4}

x = \frac{3 + 7}{4} \: and \: x = \frac{3 - 7}{4}

x = \frac{5}{2} \: and \: x = - 1

A major baseball diamond is a square with side lengths of 90 feet.

iren2701 [21]

Answer: $\bold{a)\quad 90\sqrt2\qquad \qquad b)\quad 45\sqrt2}$

<u>Step-by-step explanation:</u>

Since you are looking for the distance from home plate to second base, you are actually looking for the length of the diagonal of the square. Use the Pythagorean Theorem: a² + b² = c² where a and b are the side lengths and c is the length of the diagonal.

$90^2+90^2=c^2\\8100+8100=c^2\\16200=c^2\\\sqrt{16200}=c\\\boxed{90\sqrt2}=c\qquad \qquad \text{which is approximately 127.28}\\\\\\\\\text{Halfway between home plate and 2nd base means divide that length by 2:}\\\\\dfrac{90\sqrt2}{2}=\boxed{45\sqrt2}$
