Answer:

Here's the answer.....hope you understand....

The correct statement about Adi’s use of algebra tiles is She used the algebra tiles correctly.

Given

Adi used algebra tiles to represent the product

(-2x-2) (2x-1)

The number or expression results from the multiplication together of two or more numbers or expressions.

The correct way to find the product function is;

[tex]\rm =(-2x-2) (2x-1)\\\\=-2x(2x-1)-2(2x-1)\\\\= -4x^2+2x-4x+2\\\\= -4x^2+2x+2[/tex]

Hence, the correct statement about Adi’s use of algebra tiles is She used the algebra tiles correctly.

Answer:

Sales price of the item would be approximately $2.

Step-by-step explanation:

Answer:

26 degrees

Step-by-step explanation:

Triangle A:

So the triangle is 24 degrees and it is an isosceles triangle so the other 2 angles are equal. All the angles in a triangle add up to 180 degrees.

180-24=156 degrees

156 divided by 2 because of the 2 angles = 78 degrees

The angles in Triangle A are 78 degrees which means one corner of the Triangle X is 78 degrees as it is vertically opposite.

Triangle B:

B= 49 degrees and the triangle is isosceles as well. 49 x 2 for the other angle which would be the same is 98 degrees. We would then do

180 -98 = 82 degrees

This means the other angle in Triangle X is 82 degrees

Triangle X:

72 degrees is the top left angle and 82 degrees is the top right angle so you do 72+82= 154 degrees

180-154= 26 degrees

Step-by-step explanation:

Answer:

g[f(-2)] = 7

Step-by-step explanation:

f(x) = x^2

g(x) = 3x – 5

g[f(-2)]

First find f(-2) = (-2)^2 = 4

Then find g(4) = 3(3) -5 = 12-5 = 7

[tex]f(x)=x^2;g(x)=3x-5\\\\g[f(-2)]=3\times (f(-2))^2-5=3\times(-2)^2-5=3\times4-5=7[/tex]

Answer:

10 hours

Step-by-step explanation:

12 hours theater = $96.00

10 hours car wash = $85.00

total = 22hours = $181.00

The interest to be paid after 2 years is $765.84

The total interest to be paid after 4 years is  $1531.68

Simple interest rate is the interest that is paid only on the principal portion of a loan. This means that the debtor does not pays interest on the interest rate already accrued.

Simple interest = principal x time x interest rate

$9573 x 2 x 0,04 =$765.84

$9573 x 4 x 0,04 = $1531.68

Answer:

x/y=8/y-1/y-->x/y=8-1 /y -->x/y=7/y-->x×y=y×7-->xy=7y -->x=7y/y-->x=7Answer

Answer:

300 cents or $3

Step-by-step explanation:

Let p be the cost of one pen and m be the cost of one mechanical pencil. We can use this to set up a system of equations:

4p+6m=1620 (convert $16.20 to cents by multiplying it by 100)

m=70

We can solve this using substitution (substitute 70 for m):

4p+6(70)=1620

4p+420=1620

Subtract 420 from both sides

4p=1200

Divide both sides by 4

p=300 cents or $3

Answer:

The answer is n = -14 .

Step-by-step explanation:

4 = 1/2(n + 22)

4 = 1/2n + 11

-7 = 1/2n

-7 / 1/2 = -14 = n

To check your work:

4 = 1/2(-14 + 22)

4 = 1/2(8)

4 = 4

Equivalent expressions are expressions that have equal values

The value of x is 25/6

From the question, the values of ac and ec are equivalent

So, we have:

8x - 14 = 2x + 11

Collect like terms

8x - 2x = 14 + 11

Evaluate the like terms

6x = 25

Divide both sides by 6

x = 25/6

Hence, the value of x is 25/6
