Answer:
2(x - 2)(2x + 1)
Step-by-step explanation:
Given
4x² - 6x - 4 ← factor out 2 from each term
= 2(2x² - 3x - 2)
To factor the quadratic inside the parenthesis
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × - 2 = - 4 and sum = - 3
The factors are - 4 and + 1
Use these factors to split the x term
2x² - 4x + x - 2 ( factor the first/second and third/fourth terms )
= 2x(x - 2) + 1(x - 2) ← factor out (x - 2)
= (x - 2)(2x + 1)
Hence
4x² - 6x - 4 = 2(x - 2)(2x + 1) ← in factored form
Answer:
(-1,-1)
Step-by-step explanation:
finding y
-6x + 5y = 1
+ (6x + 4y = -10)
---------------------------
9y = -9
y = -1
finding x
-6x + 5(-1) = 1
-6x - 5 = 1
+ 5 = +5
-6x = 6
x= -1
If the volume of each brick will be 64 cubic centimeters. Then the mass of each brick will be 192 grams.
<h3>What is density?</h3>
Density is defined as the mass per unit volume. It is an important parameter in order to understand the fluid and its properties. Its unit is kg/m³.
The mass and density relation is given as
mass = density × volume
A construction company needs to transport 500 bricks. The dimensions of each brick are 2 cm by 4 cm by 8 cm.
The density of each brick is 3 g/cm³.
Then the mass of each brick will be
The volume of each brick will be
V = 2 x 4 x 8
V = 64 cm³
Then the mass will be
m = 3 x 64
m = 192 gram

Answer:
yes, yes, no, yes
Step-by-step explanation:
Answer:
<u>-335670</u>
Step-by-step explanation:
<u>Given</u> :
- a₁ = 2
<u>Solving</u> :
- Sum of an arithmetic sequence is given by
- S₃₃₅ = 335/2 x 2(2) + (335 - 1)(-3)
- S₃₃₅ = 335/2 x -4008
- S₃₃₅ = 335 x -2004
- S₃₃₅ = <u>-335670</u>
