Answer:
Step-by-step explanation:
hello :
(4x+3)(2x-5)=0
4x+3=0 or 2x-5=0
x= -3/4 or x=5/2
3•2•7=42•2=84
12•10•7=840
84+840=924in^3
Answer:
x = 10
Step-by-step explanation:
Given
14x - 7 = 133 ( add 7 to both sides )

x = 10
Answer:
second option
Step-by-step explanation:
Using the rule of radicals
× ⇔
Simplifying the radicals
=
= × × ×
= 3 × × x ×
= 3x
-------------------------------
=
= × × ×
= 2 × × x ×
= 2x
---------------------------------------
Thus
3 × 3x - 2 × 2x
= 9x - 4x
= 5x
