Answer:

a) 3x^2 + x - 2

b) 28m

Step-by-step explanation:

a) Since the Area for a normal square is b*l (base x length)

Do the same with this (Using FOIL ig)

(3x - 2) * (x + 1)

3x^2 + 3x - 2x - 2

3x^2 + x - 2

b) Since it's asking us to find out what the number will be while x = 3m, just substitute 3 for every "x" in the answer we got for a

3(3)^2 + (3) - 2

3(9) + (3) - 2

27 + 3 - 2

30 - 2

28m

Therefore the actual area of this rectangle is 28m

Answer:

Step-by-step explanation:

6x - 5 + 3x - 4 = 180     {Supplementary angles}

6x + 3x - 5 - 4 = 180

Combine like terms

9x - 9 = 180

Add 9 to both sides

9x = 180 + 9

9x = 189

Divide both sides by 9

 x = 189/9

x = 21

They are congruent to one another because both triangles have all equal sides. Therefore they are congruent.

Step-by-step explanation:

Answer and Step-by-step explanation:

To figure out the problem, we first need to know what supplementary means. In this question, supplementary (angles) is when two angles are next to each other, and when added together, they add up to 180 degrees.

By looking at the image, we see that angle 1 is next to angles 2 and 5.

Angles 1 and 2 don't look like they will add up to 180 degrees.

Angles 1 and 5 look like they will add up to 180 degrees.

A way to find supplementary angles is by looking at lines that go straight across, with a line intersecting the middle of the line to form the supplementary angles.

Step-by-step explanation:

Answer:Y = 3x2+ 4

When equation is in the form of y = Ax2 + Bx + C, it is in standard form.

A = 3, B = 0

Since A is positive, the graph opens upward.

Vertex is the lowest point on the graph.

The x coordinate of the vertex occurs at -B/2A

X =-B/2A = -0/2(3) = 0

To find the y-coordinate, we substitute 0 and solve for y

Y = 3(0)2 + 4 = 4

The vertex is at (0,4) ... the lowest point on the graph

From here, you can construct a table of values for x, and solve for y to obtain points on the graph.

Good x values to pick are -2, -1, 1, and 2

The domain is all the x-values for which the function is defined, The function is defined for all real values of x.

The domain is all real numbers. { x | x is a real number }

The range is all the y values obtained from input of the x-values.

The smallest y value is 4, the largest is positive infinity.

The range is all real numbers ≥ 4. { y | y ≥ 4 }

Answer:

A (0,0)

Step-by-step explanation:

When a function intersects the y-axis then the point of intersection is called y-intercept of the function,

Also, for y-intercept x = 0.

That is, if f(x) is the function then its y-intercept is (0, f(0) )

By the given table for x = 0, f(x) = 0

Hence, the y-intercept of the given function is (0,0),

Option A is correct.

So, to quote Sonic the Hedgehog from the movie Sonic the Hedgehog:

Answer: There are 70 women and 35 men.

Step-by-step explanation:

105 divided by 3 is 35 and 105 - 35 is 80.

The currency called the U.S dollar can be split into smaller forms or currency value of itself. Examples of these smaller forms are: dimes, nickels, pennies, and quarters.

Tammy has 23 nickels and 12 quarters.

Let's represent the number of:

Nickels = n

Quarters = q

It is important to note that the value of:

1 nickel = $0.05

1 quarter = $0.25

Tammy has 35 coins nickels and quarters. This statement can be represented using an algebraic equation below:

n + q = 35

This can be rewritten as :

n = 35 - q

In all, she has $4.15. This statement can be represented using an algebraic equation below:

0.05n + 0.25q = 4.15

We substitute 35 - q for n in the above equation.

0.05(35 - q) + 0.25q = 4.15

1.75 - 0.05q + 0.25q = 4.15

Collect like terms

- 0.05q + 0.25q = 4.15 - 1.75

0.2q = 2.4

Divide both sides by 0.2

0.2q/0.2 = 2.4/0.2

q = 12

Therefore, the number of quarters Tammy has is 12.

Solving for the number of nickels, we have the equation:

n = 35 - q

n = 35 - 12

n = 23

Therefore, the number of nickels Tammy has is 23.

Answer:

51°

Step-by-step explanation:

We know that all angles in a triangle add up to 180°

We have one of them, 68° for now.

We also know the angle on the outside of the triangle that forms with one side being extended. That side is a straight line (180°)

Which means the interior angle there would be 180-119 = 61°

This means that we have 2 out of 3 angles now. Now we just add them up and subtract them from 180°.

180° - (68+61) = 51° is our final answer.

Let me know if that makes sense, or if you have any other questions.
