Answer:

4y2 - 189

Step-by-step explanation:

Step 1 :

Equation at the end of step 1 :

(((((4x+3y2)-724)+524)+11)-4x)+y2

Step 2 :

Trying to factor as a Difference of Squares :

2.1 Factoring: 4y2-189

Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A2 - AB + BA - B2 =

A2 - AB + AB - B2 =

A2 - B2

Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : 4 is the square of 2

Check : 189 is not a square !!

Ruling : Binomial can not be factored as the difference of two perfect squares.

Final result :

4y2 - 189

Put like terms together. (4x-4x) (3y2+y2) (-725+524+11). Then do the math for them. (0) (3y^(2)4) (190). So the answer is 3y^(2)4+190

"The perimeter P..." gives us one variable to work with.

"is" in this context almost always means "equals".

"the sum" we know we will be adding.

"twice the length l" gives us a variable and a coefficient.

"twice the width w" gives us a variable and a coefficient.

The equation for this is P=2l+2w

I hope in the future you can remember these tips! :)

We can use the formula density mass over volume to find the density of a substance square metal plate has a density of 10.7 g of

sweet-ann [11.9K]

Answer: The volume of given substance is $2.2 cm^{3}$ .

Step-by-step explanation:

Given: Density = 10.7 $g/cm^{3}$

Mass = 23.54 g

Density of a substance is the mass of substance divided by its volume.

Mathematically, $Density = \frac{mass}{volume}$

Substitute the values into above formula to calculate volume as follows.

$Density = \frac{mass}{volume}\\10.7 g/cm^{3} = \frac{23.54 g}{volume}\\volume = \frac{23.54 g}{10.7 g/cm^{3}}\\= 2.2 cm^{3}$

Thus, we can conclude that the volume of given substance is $2.2 cm^{3}$ .

Can somebody help me

Plot the intercepts:

y=-1

x=?

to find the x intercept, you dont solve the equation as it is solved in the slope-intercept form. instead, you simply plug in 0 for y:

0=1/4x-4

0=1/4x-4+4

4=1/4x

4/1/4=1/4x

1/4=0.25

x=16

revise:

y=(0, -1)

x=(16,0)

graph the slope for y=-1/2x-1: start from say point (0,-1)

graph the slope for y=1/4x-4: start from say point (16,0) ; you can just ise the intercept (0,-4) since the graph is diluted small...anyways

the points intersect at (4, -3) so thats the solution to the equations

NOTE: when graphing slopes that are negative either the numerator or the denominator can be graphed negative. so I graphed the first equation with the numerator as the positive and the denominator as the negative : rise= 1 ; run: -2. once i got to the end of the provided graph i started from the -1 y-intercept again and graphed the equation using: rise=-1; run=2

*graphing messes me up, too*
