expand and simplify {3x+2}{x-1}

Answers

Answer:

{3x+2}{x-1} = 3x²-x-2

Step-by-step explanation:

The given expression is :

{3x+2}{x-1}

We can solve it as follows :

{3x+2}{x-1} = 3x(x)+3x(-1) +2(x) +2(-1)

= 3x²-3x+2x-2

= 3x²-x-2

So, the expand form of the given expression is 3x²-x-2.

i’m so confused please help

Answers

Answer:

BCD = 90˚

ABD = 16˚

CBE = 74˚

ADE = 74˚

AEB = 148˚

DEA = 32˚

Step-by-step explanation:

BCD: I suppose that’s a rectangle, and all rectangles have four right (90˚) angles.

ABD: alternate interior angles are congruent, so ABD is congruent to BDC (16˚).

CBE: Complementary angles add up to 90˚, so just subtract ABD (16˚) from 90˚ to equal 74˚.

ADE: Same this as CBE for same reason.

AEB: You need to find DEC first for this. To find DEC, add BDC and ACD together to get 32˚, then subtract that from 180˚ to find the answer (148˚). This is because all triangles have a 3 interior angle measure sum of 180˚. (And vertical angles are congruent).

DEA: Subtract AEB from 180˚ because they’re supplementary angles.

Hope this helps :)

cut a 60 cm ribbon into such that one part is one third of the other half

Answers

Answer:

15cm and 45cm

Step-by-step explanation:

If one part is one third of the other, then the long one is three times as long as the short one.

If the short one has length x

x + 3x = 60cm

4x = 60cm

x = 15cm

So short one is 15cm and the long one is 3*15cm = 45cm

140 % of what number is 14?

Help

Answers

Answer:

Step-by-step explanation:

I simply divided 140/14 and got 10! Hope this helps :)

The 140 percentage of the number 10 is 14

Given data ,

To find the number that is 140% of another number, we can set up the equation:

140% of x = 14

So , 140 percentage of the number x = 14

To solve for x, we need to convert 140% to its decimal form, which is 1.40:

1.40 * x = 14

Now we can solve for x by dividing both sides of the equation by 1.40:

x = 14 / 1.40

Dividing 14 by 1.40 gives us:

On simplifying , we get

x = 10

Therefore , the value of x = 10

Hence , 140 percentage of 10 is equal to 14

Maggie wants to buy a new energyefficient refrigerator. Her old refrigerator uses about 1200 kWh per year,while the new one would use about 400 kWh per year. Approximately how much money would Maggie saveper year if she buys the new refrigerator?

Answers

Answer:

800 Kwh

Step-by-step explanation:

To solve this problem, we need to find the difference in energy saved and then multiply by the cost of 1kWh of electricity

How much did Maggie save?

Let's first of all calculate the the difference in energy saved

Data;

old refrigerator = 1200kWhnew refrigerator = 400kWh

[tex]1200 - 400 = 800kWh[/tex]

Maggie would've saved 800kWh in one year.

But since we were not given a standard cost of electricity, we would assume that 1kWh will cost $1.

So, to determine how much she must've saved, we simply multiply $1 by 800kWh

[tex]1 * 800 = $800[/tex]

Using our assumptions, she would've saved $800 in one year.

What is the slope of (-4,6) and (2,-5)

Answers

Answer:

-11/6

Step-by-step explanation:

Slope can be found with this equation:

(y₁ - y₂) / (x₁ - x₂)

What this essentially tells us to do is to put one set of the x and y coordinates into x₁ and y₁, respectfully. Then, put the other set of x and y points as x₂ and y₂.

With this scenerio, we can substitute the given points into the formula.

(6 - (-5)) / (-4 - 2) =

(6 + 5 ) / (-6) =

11 / (-6) =

-11/6

The slope is - 11/6

The slope is equal to y2 - y1 over x2 - x1.
The answer is -11/6
