Answer:

C

Step-by-step explanation:

First of all we can simplify the the first therm because a property of power says that we can simplify a power of power by multiply the exponents

a^4b^8c^2

For the same property 2c^5 becomes 8c^15

now we have

(a^4b^8c^2)(6a^3b)(8c^15)/4a^6b^12c^3

if we simplify the numbers we can obtain

(a^4b^8c^2)(6a^3b)(2c^15)/a^6b^12c^3

If we simplify the parameters we can obtain

12ac^14/b^3

Urgent please help. will mark brainliest.
mihalych1998 [28]

Answer:

x= -1

Step-by-step explanation:

p= x² +4x -2 -----(1)

q= 2x -1 ------(2)

q -p= 2 -----(3)

Substitute (1) and (2) into (3):

2x -1 -(x² +4x -2)= 2

2x -1 -x² -4x +2= 2 <em>(</em><em>Expand</em><em> </em><em>bracket</em><em>)</em>

-x² -2x +1=2 <em>(</em><em>S</em><em>implify</em><em>)</em>

x² +2x +2 -1= 0 <em>(</em><em>Bring</em><em> </em><em>all</em><em> </em><em>terms</em><em> </em><em>to</em><em> </em><em>one</em><em> </em><em>side</em><em>)</em>

x² +2x +1= 0

(x +1)²= 0 <em>(</em><em>Factorise</em><em>)</em>

x +1= 0 <em>(</em><em>Square</em><em> </em><em>root</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>

x= -1 <em>(</em><em>-1</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>

How do i solve 4=v+5/3
mina [271]

Answer:

<u>= 7</u>

Step-by-step explanation:

switch sides

v+5/3 =4

multiply both sides by 3

3(v+5)/3=4 times 3

simplify

v+5=12

subtract 5 from both sides

v+5-5=12-5

simplify

v=7
