2(x - 3) + 9 = 3(x + 1) + X?​

Mathematics
1 answer:
kow [346]3 years ago
5 0

Answer:

x = -X    OR     x = 0

Step-by-step explanation:

I don't know if the capital 'X' was a different variable, so I did both calculations.

2(x - 3) + 9 = 3(x + 1) + X

= 2x - 6 + 9 = 3x + 3 + X

= 2x + 3 = X + 3x + 3

= -x = X

= x = -X

2(x - 3) + 9 = 3(x + 1) + x

= 2x - 6 + 9 = 3x + 3 + x

= 2x + 3 = 4x + 3

= -2x = 0

= x = 0

A flying disc has a radius of 10 inches. What is the area of one side of the flying disc to the nearest square inch? Use 3.14 as
oksano4ka [1.4K]

<u>Answer:</u>

The area of one side of a disc is 314 square inches  

<u>Explanation:</u>

Given the radius of the disc is 10 inches

The disc is in circular shape and the area of a circle is determined by

A = \pi r^2, where

A is the area and r is the radius and π = 3.14

Substituting values in the formula,

A = 3.14 \times(10)^2

A = 3.14 \times100 = 341 sq. inches

Therefore, the area of one side of a disc is 314 square inches

A<br> Solve for x. Write both solutions, separated by<br> comma.<br> 4x2 + 5x – 6= 0
Kamila [148]

Answer: x1 = -2, x2 = 3/4

Step-by-step explanation:

4x^2 + 5x -6 = 0

4x^2 + 8x -3x -6 = 0

4x(x+2)-3(x+2)=0

(x+2)(4x-3) = 0

x+2 = 0: x = -2

4x-3 = 0: x = 3/4
