-4(3-6)·(-3)²=______

Answer:

(ab + cd + ac - bd)(ab + cd - ac + bd)

Step-by-step explanation:

(ab + cd)² - (ac - bd)² ← is a difference of squares and factors in general as

a² - b² = (a + b)(a - b)

Here a = ab + cd and b = ac - bd , then

= (ab + cd + ac - bd)(ab + cd - (ac - bd))

= (ab + cd + ac - bd)(ab + cd - ac + bd)

Answer:

-2x+2

Step-by-step explanation:

Answer:

-2x+2 because you would have to distribute

Hey there!

The first expression is

5x+15

The equivalent expressions are

5(x+3)

- the opposite of the Distributive Property: 5(x+3)=5x+15

Plus

isn't 5*x+5*3 the same as 5x+15?

Yeah, it is :)

Hence, the equivalent expressions are

[tex]\boxed{\boxed{\bold{Option\;A \;and\;Option\;B}}}[/tex]

[tex]\rule{200}{2}[/tex]

In order to simplify this expression, we need to combine like terms:

11+12y-3-y

The y's are like terms:

11+12y-y-3

11+11y-3

Can you spot any other like terms here? That's right, 11 and -3:

11-3+11y

8+11y

Hence, the equivalent expression is

[tex]\boxed{\boxed{\bold{11y+8}}}[/tex]

Hope everything is clear.

Let me know if you have any other questions; if so, please comment.

The equation y = 3x - 5 is an illustration of a linear equation

The slope is 3, and the y-intercept is -5

The equation of the table is given as:

y = 3x - 5

When x = -1, we have:

y = 3(-1) - 5 = -8

When x = 0, we have:

y = 3(0) - 5 = -5

When x = 1, we have:

y = 3(1) - 5 = -2

So, the complete table is:

x     y

-1    -8

0      -5

1       -2

A linear equation is represented as:

y = mx + b

Where:

m represents the slope and b represents the y-intercept.

By comparison, we have:

m = 3, and b = -5

Hence, the slope is 3, and the y-intercept is -5

Answer:

x=-1 & y=-9

Step-by-step explanation:

7x-3y=20 ⇒(1)

y=5x-4 ⇒(2)

Multiplying (2) by 3

3y=15x-12 ⇒(3)

Add (1) and (3)

7x-3y+3y=20+15x-12

7x=15x+8

-8x=8

Substitute by x at (2)

y=5(-1)-4= -5-4=-9

x=-1 and y=-9

Answer:

<2, <5, and <7.

Step-by-step explanation:

<2 and 72°, are vertical angles. Vertical angles are congruent. Therefore, <2 ≅ 72°.

<7 and 72° are corresponding angles. Corresponding angles are congruent, therefore, <7 ≅ 72°.

<5 and 72° are alternate interior angles. Alternate interior angles are congruent, therefore, <5 ≅ 72°.

Angles that are congruent to 72° are <2, <5, and <7.

The equation [tex]\rm \sqrt{x^2 + 81} = x + 10[/tex] is equivalent to [tex]\rm x^2 + 81 = x^2 + 20x + 100[/tex]. Then the correct option is D.

It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.

The equation is given below.

[tex]\rm \sqrt{x^2 + 81} = x + 10[/tex]

Squaring both sides, we have

[tex]\rm (\sqrt{x^2 + 81})^2 = (x + 10)^2\\\\x^2 \ \ +\ \ 81 \ \ = x^2 + 20x + 100[/tex]

Thus, the equation [tex]\rm \sqrt{x^2 + 81} = x + 10[/tex] is equivalent to [tex]\rm x^2 + 81 = x^2 + 20x + 100[/tex]. Then the correct option is D.

Answer:

The answer is 16x-4x+1, give me brainliest answer

Answer:

–16(x2 – 3x – 4)

first we have to distribuite

-16x^2+48x+64

then we have to look for a number that goes into all of these which is -16

x^2-3x-4

then multiply the first by the last

-4x^2

then we have to find a two number that adds to make -3 and multiples to make -4x2

now lets list the factors

2*2

4*1

then lets just plug in

(x^2+x)(-4x-4)

now we have to factor out

x(x+1)-4(x+1)

-16(x-4)(x+1)

Answer:

X= -10

Step-by-step explanation:

Answer:

Angle Relationship: Alternate exterior angles

x = -10

Angle measurement: 51 °

Step-by-step explanation:

These angles are located "outside" the two parallel lines but on opposite sides of the transversal, therefore they are alternate exterior angles.

Alternate exterior angles are congruent, therefore the angle must be 51 °

51 = 61 + x

subtract 61 from both sides

x = 10

Answer:

16 inches

Step-by-step explanation:

1 foot is equivalent to 12 inches so the puppy will grow 16 more inches which is equal to 28 inches.

B5 + C9 = 164

Split the numbers.

B0 +C0 +14 = 164.

B0 + C0 = 150

B + C = 15

B cannot be 1, 2, 3, 4, or 5 because that forces C to be a two digit number and C only represents 1 digit.

B cannot be 6 or 9 because they are present.

B can only be 7 or 8. C can also be 7 or 8.

Therefore, B = 7  and C = 8, OR B = 8 and C = 7.
