12. Multiply the following binomials:
a. (x + 3)(x - 4)
b. (s - 2)(2s - 12)
c. (4s - 12)(2s + 4)
d. (2x - 4)(2x - 4)

Answers

Answer 1

Answer:

a) x^2 - x -12

b) 2s^2 - 16s + 24

c) 8s^2 - 8s -48

d) 4x^2 - 16x + 16

Answer 2

Answer:

a. x^2 - x - 12

b. 2s^2 - 16s + 24

c. 8s^2 - 8 - 48

d. 4x^2 - 16 + 16

Step-by-step explanation:

You need to use distributive property find the answer.

(x + 3)(x - 4)

>> (x)(x) = x^2

>>(x)(-4) = -4x

(3)(x) = 3x

(3)(-4) = -12

The result will be x^2 -4x + 3x -12

You can simplify this by adding the like terms:

x^2 -4x + 3x -12

>> x^2 - x - 12

Just do the same for the rest of them by using distributive property.

Hope this helps! Have a great day! Also, let me know if you need an explanation for the rest of them too!

Answers

Answer:

7 units from (-3,2)(,2)and(,2)

Step-by-step explanation:

The purpose of this task is for students to solve a mathematical problem using points in the coordinate plane. This task also helps lay the foundation for understanding operations on signed numbers without formally introducing those notions, which are not expected until 7th grade (see 7.NS.1). Students will not have the full machinery needed to find distances between two arbitrary points in the plane until they have studied the Pythagorean Theorem in 8th grade. However, it is straightforward for them to find horizontal and vertical distances, which mirrors how one might represent sums and differences of signed numbers on a number line. The solution for the first part shows how these questions can be represented using absolute values (as described in standard 6.NS.C.8), although students are unlikely to make this connection without being asked to do so. If students are asked to solve this problem on their own first, it could be used to launch a discussion of the relationship between the the absolute value of coordinates of points in the plane and their distance to the respective axes.

Please note that students will have to assume that the points have integer coordinates, which is reasonable but worth mentioning.

Solution

The distance between points B and C is 5 units, as indicated below.

We can determine the distance between points B and C by counting the units between the two points since they are on the same vertical line which happens to be a grid line.

We can also note that the coordinates for B are (3,2) and so it is |2| units above the x-axis. Similarly, the coordinates for C are (3,−3), so it is |-3| units below the x-axis. Thus, the distance between B and C is

|2|+|−3|=5

units.

The distance between points D and B is 7 units, as indicated below.

The distance between points D and E is 4 units, as indicated below.

Point C is the only one of points A,…E that is both 4 units away from (−1,−3) and 2 units away from (3,−1). There is another point that satisfies these two criteria (which is the other intersection point of the circle of radius 4 and circle of radius 2 shown below), but it does not have integer coordinates and is not one of the points identified in the task

Simplify:

-30x^9/10x^17

Answers

Answer:

-3/x^8

Step-by-step explanation:

First, we simplify -30/10 which will be -3.

Next, we simplify x^9/x^17 which will be x^-8, since when dividing exponents, you subtract them. Sorry if this sounds confusing, but if this helps you better understand it, then here you go: I mean that y^n/y^z = y^(n-z).

x^-8 = 1/(x^8), and to find our answer, we multiply this by -3 to get an answer of:

-3/x^8

Trying to factor by splitting the middle term

2.1 Factoring 2d2-3d-2

The first term is, 2d2 its coefficient is 2 .
The middle term is, -3d its coefficient is -3 .
The last term, "the constant", is -2

Step-1 : Multiply the coefficient of the first term by the constant 2 • -2 = -4

Step-2 : Find two factors of -4 whose sum equals the coefficient of the middle term, which is -3 .

-4 + 1 = -3 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -4 and 1
2d2 - 4d + 1d - 2

Step-4 : Add up the first 2 terms, pulling out like factors :
2d • (d-2)
Add up the last 2 terms, pulling out common factors :
1 • (d-2)
Step-5 : Add up the four terms of step 4 :
(2d+1) • (d-2)
Which is the desired factorization

Final result :
(d - 2) • (2d + 1)

Answers

Answer:

The height of the object after 3 seconds is 45 feets.

Step-by-step explanation:

The height of an object thrown into the air with an initial upward velocity of 63 feet per second is given as

Where, h(t) is height of the object in feet and t is the time in seconds.

We have to find the height of the object after 3 seconds. So, substitute t=3.

Therefore height of the object after 3 seconds is 45 feets.

10/10 times 13 is 13. Yes

The expressions greater or equal to 13 are B and D.

What is an expression?

An expression in math is a statement having minimum of two numbers, or variables, or both and an operator connecting them.

Given are expressions we need to determine expressions having values equal to or greater than 13,

So,

5/6 and 3/4 are numbers less than 1 if we multiply any number with them it will decrease its value,

So, the expression 4 x 13 and 10/10 x 13 will be the expressions having values equal to or greater than 13.

Hence the expressions greater or equal to 13 are B and D.
