What is the area of the triangle below

Answer:

the first one is 8x-2a

second is 4x+6y

You should combine like factors- factors with the same variable and get your answer.

Answer:

3x-2a+5x+4a

8x + 2a

6x-2x+8y-2y

4x + 6y

explanation:

These are about combining "like terms" so you put the x-terms together by adding or subtracting the "coefficients," the numbers attached to the variables. Combine only terms that have the same letters when adding or subtracting.

Answer:

D

Step-by-step explanation:

Answer:

X=-6

Step-by-step explanation:

4(1−x)+3x=−2(x+1)

(4)(1)+(4)(−x)+3x=(−2)(x)+(−2)(1)(Distribute)

4+−4x+3x=−2x+−2

(−4x+3x)+(4)=−2x−2(Combine Like Terms)

−x+4=−2x−2

−x+4=−2x−2

Step 2: Add 2x to both sides.

−x+4+2x=−2x−2+2x

x+4=−2

Step 3: Subtract 4 from both sides.

x+4−4=−2−4

x=−6

Answer:

x=−6

Answer:

x=-2

Step-by-step explanation:

4 - 4x + 3x=-2x -2

4 -1x=-2x -2

4= -1x -2

2=-1x

x=-2

Answer: 88 in2

Step-by-step explanation:

The side of the can, which when "unrolled" is a rectangle, with width = height of the cylinder (7 in); and length = Circumference = 2π radius

Surface area of the curved surface of the can = 2π (diameter/2) x height

Replacing with the values given:

S = 2π (4/2) x 7 = 2π (2) x 7 = 88 in2

Answer:

B.

Step-by-step explanation:

The dots are completely random.

Answer:

A. [–1, 1]

Step-by-step explanation:

The range is the values that the output can take

The values that sin can take go from -1 to 1 inclusive

Given that in 2005 a house was purchases for 280,000 and was later sold in 2013 for 334,000, determine the increase value of the house and what the price of the house will be in 2018.

First, we subtract the two values of the house on both dates.

334,000 - 280,000 = 54,000

Then, divide the difference by the amount of years from 2005 to 2013.

54,000/8 = 6,750

Since, it says the value increases at a constant rate, this indicates that it is a linear function.

So, the linear function would start at 280,000 as the y-intercept and the slope is 6,750.

Linear Function: y = 6750x + 280,000

Lastly, to find the price of the house in 2018, we just need to plug in 13 for x since x represents the years.

y = 6750x + 280,000

Plug in 13 for x.

y = 6750(13) + 280,000

y = 87750 + 280,000

y = 367,750

Thus, the value of the house in 2018 is $367,750.

Answer:

Range: 12

Step-by-step explanation:

65, 66, 67, 68, 71, 73, 74, 77, 77, 77

Formula:

Range: highest value - lowest value = final answer

Range: 77 - 65 = 12

Answer:

Yes

Step-by-step explanation:

Only if its sold by a person and not a company, most people refer to that as an offer.

Answer:

Yup, it can

Step-by-step explanation:

In newspapers or online people do many offers/sales to get you to buy something. For example, let's say you see Gardening Services, that would be considered as an offer, because the salesperson or company is selling you something. Online, you could be sold offers as well, like a new phone, a house, etc.

Answer:

Step-by-step explanation:

length = 5 1/4 = 21/4 inches

Width = 2 1/2 = 5/2 inches

Height = 2 inches

Volume of rectangular prism = length * width * height

                     [tex]= \frac{21}{4}*\frac{5}{2}*2\\\\= \frac{21}{4}*5\\\\=\frac{105}{4}[/tex]

                     = 26.25 cubic inches

Answer:

26 1/4 i think

Step-by-step explanation:

5 1/4 times 2 1/2 times 2 is 26 2/8 but then you simplify it and you get 26 1/4

Answer:

a) I (interest) = $ 20,311.62

b) ≈ 8.03%

A = $ 44,061.62

A = P + I where

P (principal) = $ 23,750.00

I (interest) = $ 20,311.62

A = $ 44,061.62

____________________________________

A = $ 43,959.59

A = P + I where

P (principal) = $ 23,750.00

Answer:

Step-by-step explanation:

upper block:

length (l) = 120 cm

Width (w) = 30 cm

Height (h) = 60 cm

Volume of upper block = l * w * h

                                      = 120 * 30 *60

                                     = 216,000 cm³

Lower Block

l = 120 cm

w = 30 cm

h = 30 cm

Volume of lower block = 120 * 30 * 30

                                      = 108,000 cm³

Volume of steps = 216,000 + 108,000 = 324,000 cm³
