Part A: 
(3x+5)+(3x+5)+(4x-3)+(4x-3)=p
3x+3x+4x+4x=14x
5+5+-3+-3=4
14x+4=p
     -4    -4
14x=p-4
----  -----
14    14

x=1/4 p + -2/7

14(1/4 p +-2/7) +4=p
14(0.25p + 0.28571428571)+4=p
3.5 + 3.99999999994 + 4=p
11.4999999999=p

This may not help by no harm in trying.

You buy a cylindrical container of salt with a diameter of 3.25 inches and a height of 5 inches. Your salt shaker is a cylinder
Sphinxa [80]
First calculate volume of the cylindrical container: Pi * R2 * H; where Pi is 22/7 or 3.147, R is the radius and H is the height of the container.

Vol of the cylindrical container: 3.147 * (3.25/2) * (3.25/2)* 5 = 41.55 inch 3

Volume of the shaker using the above principle:
3.147 * (1/2) * (1/2) * 1.5 = 1.18 inch 3

Number of times it can fill the salt shaker will be the ratio of the volumes:

= Volume of the cylindrical container divided by the volume of the shaker = 41.55 divided by 1.18

Answer is 35 times if rounded in absolute number.

What is the polynomial function of lowest degree with rational real coefficients, and roots -3 and square root of 6?
telo118 [61]

9514 1404 393

Answer:

  f(x) = x³ +3x² -6x -18

Step-by-step explanation:

In order for there to be a root of √6, there must be a factor of (x-√6). In order for there to be rational coefficients, there needs to be another factor of (x+√6) in the minimal polynomial. Then the minimal polynomial with the required roots is ...

  f(x) = (x +3)(x -√6)(x +√6) = (x +3)(x² -6)

  f(x) = x³ +3x² -6x -18

Find the surface area of the square pyramid 8mm 6mm
bija089 [108]

Answer:

136 mm²

Step-by-step explanation:

A=a^{2} +2a\sqrt{\frac{a^{2} }{4} } +h^{2}

A=6^{2} +2(6)\sqrt{\frac{6^{2} }{4} } +8^{2}

A=36 +12\sqrt{\frac{36 }{4} } +64

A=36 +12\sqrt{9 } +64

A=36 +12(3)+64

A=36 +36+64

A = 136
