which expression is equivalent to -3.5(4x - 3) ? And why?

Answer:

Step 1

Step-by-step explanation:

They're all wrong expansions but step 1 was where he made his first error... He shifted the bracket putting 3x inside the bracket... While the other steps the first expansion of 3x eliminating the bracket was correct.

The correct expansion is meant to be 3x + 21 + 5 = 3x + 26

Answer:

(1.5, 2.5)

Step-by-step explanation:

A. The area is 4 square units

B. The description is below

======================================================

Break the figure into two parts along the dashed line. So we get a triangle on the left and a rectangle on the right.

The triangle has horizontal base of 3-1 = 2, and height 2. It's area is base*height/2 = 2*2/2 = 4/2 = 2 square units.

The rectangle is 1 by 2, so it's area is length*width = 1*2 = 2 square units.

Combine the two smaller areas to get the overall area: 2+2 = 4 square units

--------

As an alternative, you can use the trapezoid area formula

b1 = 3 and b2 = 1 are the two parallel bases

h = 2 is the height

A = area of trapezoid

A = h*(b1+b2)/2

A = 2*(3+1)/2

A = 2*4/2

A = 8/2

A = 4 square units

Answer:

5A)36 5b)30(mark as brainliest)

Step-by-step explanation:

5a)6+6+6+6+12 = 36

5b)36-8=28

28+2 = 30

Answer:

a: The answer is 36 units squared

b: You would lose four square units

Step-by-step explanation:

a: You can count the pieces showing, but you also have to add the amount you cannot see, which would give you a total of 36 units squared (since it doesn't say what each unit is represented by

b: The bottom pieces that originally were not showing would now be showing, but you would lose the ones above it. These cancel out from each other. There are 4 other sides that are now no longer showing since the others that are still showing still were anyways, so there are 4 units squared missing from the surface area when you remove the top two blocks.

Answer:

4 PM

Step-by-step explanation:

At 4 PM the temperature reached 68 degrees Fahrenheit??

Answer:

[tex]4\:\text{PM}[/tex]

Step-by-step explanation:

The first point where [tex]y=68[/tex] occurs at [tex]x=4[/tex], hence [tex]\boxed{4\:\text{PM}}[/tex]

I think the answer should be b, since y=3 when x=0, according to the option B.

y = x + 3, B

Answer:

12.56

Step-by-step explanation:

the equation for a circumference is C=2pi r

C=2*3.14*2

2*3.14=6.28

6.28*2=12.56

Answer: I think 10

Step-by-step explanation: cuz area is length x height and basically you just do square root of 100 Bc thags a square so the sides should be equal

Answer:

(0, -2)

Step-by-step explanation:

The x- and y-coordinates indicate the position of a point in the 2D coordinate plane relative to the origin. The coordinates are written as an ordered pair of numbers (x, y), where x indicates horizontal position and y indicates vertical position.

Example

The position of the point in the figure below is specified by the ordered pair, (6, 4). 6 is the x-coordinate and 4 is the y-coordinate of the point.

Answer:

[tex]x=\frac{23}{7}- \frac{y}{7}[/tex]

Step-by-step explanation:

2x + 3y = 12

5x - 2y = 11

2x + 3y + 5x - 2y = 11 + 12

7x + y = 23

[tex]x=\frac{23}{7}- \frac{y}{7}[/tex]

Answer:

x = -2, y = -8

Step-by-step explanation:

13(y + 6) - 6y = 22

=> 13y + 78 - 6y = 22

=> 7y = -56

=> y = -8

x = -8 + 6

=> x = -2

0.62 × 10^6 =

6.2 × 10^5

Answer

y = 0.2x − 7

Step-by-step explanation:

Find the slope first by subtracting (10, -5) and (5, -6) in slope formula, this will equal 1/5 or 0.2

Then find the y-intercept which is the point that crosses the y-axis, in this case -7 is the y-intercept

Finally format in y=mx + b for slope-intercept form

y=0.2x-7

Answer:

55 centimeters

Step-by-step explanation:

It is a right triangle which means it will add up to 90 degrees. You would start by adding 20 and 15 which is 35 and then subtract 35 from 90 to get 55. I hope this helped :)

Answer:

Number of juice boxes people drank at Williams party = 91

Step-by-step explanation:

Total juice boxes Williams bought = 114

Juice boxes left over at the party = 23

How many juice boxes did people drink at William's party?

Number of juice boxes people drank at Williams party = Total juice boxes Williams bought - Juice boxes left over at the party

= 114 - 23

= 91

Number of juice boxes people drank at Williams party = 91

Answer: Commutative property of multiplication

Answer:

/13=3.60

(a)^2+(b)^2=(c)^2

(6)^2+(3.60)^2=(c)^2

36+13=(c)^2

pythagorean theorem is (a)^2+(b)^2=(c)^2

then replace it with the given values

inverse of square is squareroot

Answer:

third side is 7 units

Step-by-step explanation:

Hi there!

the Pythagorean theorem is given as a²+b²=c², where a and b are legs (the sides that make up the right angle) and c is the hypotenuse (side that is opposite to the right angle, or in this case, the third side)

we are given the lengths of the 2 legs, and we need to find the hypotenuse

a=6

b=√13

c=unknown value

square the values of a and b, add them together, and set that to equal c squared

or in other words:

6²+(√13)²=c²

36+13=c²

(because 6*6=36; √13*√13=13)

49=c²

√49=√c²

7=c

therefore the hypotenuse is 7 units

Hope this helps!
