Write as an expression: Jones Elementary School sang 3 more than 4 times as many songs as Redwc

1 answer:

4 0

It should be 4x+3. since u don’t have the amount of songs that redwc sang, it would be a variable such as x, and the 3 more means to add. hope this helped!

What type of triangle is defined by the following set of side lengths

NARA [144]

Answer:

ACUTE TRIANGLE 

Step-by-step explanation:

If the sum of the squares of the two shorter sides of a triangle is greater than the square of the longest side, the triangle is acute. However, if the sum of the squares of the two shorter sides of a triangle is smaller than the square of the longest side, the triangle is obtuse.

Therefore, the triangle with sides 11, 9, and 7 is an acute triangle since 9² + 7² is greater than 11²

${9}^{2} \: + \: {7}^{2} > \: {11}^{2} \\ 130 > 121$

Pls i need this today help me

kondaur [170]

Answer:

Step-by-step explanation:

a) 4x² + 20 = 0

4x² = -20

x² = -20/4

x² = -5 = i² *5

x = √i²5

x = i√5

b) 4x² + 5 = -7

4x² = -7 - 5

4x² = - 12

x² = -12/4

x² = -3 = 3i²

x = i√3

c) x² + 4x + 20 = 0

a = 1 ; b =4 ; c =20

$x = \frac{-b+\sqrt{b^{2}-4ac}}{2a} and \frac{-b-\sqrt{b^{2}-4ac}}{2a};\\\\x = \frac{-4+\sqrt{16-4*1*20}}{2*1} and\frac{-4-\sqrt{16-4*1*20}}{2*1}\\\\=\frac{-4+\sqrt{16-80}}{2} and \frac{-4-\sqrt{16+80}}{2}\\\\=\frac{-4+\sqrt{-64}}{2} and \frac{-4-\sqrt{64}}{2}\\\\= \frac{-4+8i}{2} and\frac{-4-8}{2}$

= (-2 +4i) & -12/2

= (-2 + 4i) and (-6)
