Answer:

x = 3 or x = -1/4

Step-by-step explanation:

from (x-3)(4x+1) = 0

We can see that a * b = 0

so a = 0 or b = 0

thus

x - 3 = 0 or 4x + 1 = 0

we solve x = 3 or x = -1/4

aniked [119]

Answer:

none of the options

Step-by-step explanation:

4x − 5y = 2 , 10x − 21y = 10

---------

the first equation is same in all answer choices, let's check which is equivalent to second, the easy way is to consider x/y ratio which is 10/ -21

4x − 5y = 2 , 3x − y = 4

no, ratio is 3/ -1

4x − 5y = 2 , 24x − 47y = 22

no, the ratio is 24/ -47

4x − 5y = 2 , 10x + 3y = 15

no, the ratio is 10/3

4x − 5y = 2 , 14x + 26y = 12

no, the ratio is 14/26

Question:

A rectangle has a height of 2x^4 and a width of x^2+8x+15. Calculate its area.

Answer:

$Area = 2x^6 + 16x^5 + 30x^4$

Step-by-step explanation:

Given

$Height = 2x^4$

$Width = x^2 + 8x + 15$

Required

Determine the area of the rectangle

This is calculated as:

$Area = Width * Height$

$Area = (x^2 + 8x + 15) * 2x^4$

$Area = 2x^6 + 16x^5 + 30x^4$
