Answer:

(x + 3)(x - 7)

(x + 1)(x - 2)

Step-by-step explanation:

The general form of factored equations :

y = (x + a)(x + b) [it can be ±, so don't worry about that part]

===============================================================

Hence, the expressions which are in factored form :

⇒ (x + 3)(x - 7)

⇒ (x + 1)(x - 2)

Find the missing side.

Vitek1552 [10]

Answer:

Step-by-step explanation:

This is a right triangle, but note that you only know the measurement of one angle, which is 90 degrees.

Use the following formula to solve:

a² + b² = c²

In which:

a & b = shorter sides

c = hypotenuse

Plug in the corresponding numbers to the corresponding variables:

(3)² + (4)² = ?²

Solve. Remember to follow PEMDAS. First, solve the exponents, then add:

(3)² = (3 * 3) = (9)

(4)² = (4 * 4) = (16)

9 + 16 = ?²

25 = ?²

Isolate "?". Root both sides:

√(25) = √(?²)

? = √25 = √(5 * 5) = 5

Your missing side's measurement is 5.

inna [77]

Answer:

The answer to your question is: x⁴ + 4x³ + 8x² + 8x - 5

Step-by-step explanation:

(x² + 2x - 1)(x² + 2x + 5) = x⁴ + 2x³ + 5x² + 2x³ + 4x² + 10x - x² - 2x - 5

= x⁴ + 4x³ + 8x² + 8x - 5

Which list shows the integers in order from lest to greatest ? -8 , -5 , 0 , 2 , 6 0 , 2 , -5 , 6 , -8 -5 , -8 , 0 , 2 , 6 0 , -

Elina [12.6K]

Answer:

a.-8,-5,0,2,6

Step-by-step explanation:

We have to find the list which shows the integers in order from least to greatest.

We know that when we left side of zero on a number line then the values decrease and we go right side of zero then the value increases.

a.-8,-5,0,2,6

-8<-5<0<2<6

Hence, it is true.

b.0,2,-5,6,-8

-8 least and 6 is greatest

Therefore, it is false.

c.-5,-8,0,2,6

It is false.

d.0,-8,-5,2,6

It is false.

Option a is true,

Social Security numbers are of the form XYZ - MN - ABCD

Part A:

The first three digits XYZ are referred to as the area number

X is a number 1 - 7 (1, 2, 3, 4, 5, 6, 7)

That means we have 7 choices for X

Y and Z can be any number 0 - 9 (0, 1, 2, 3, 4, 5, 6, 7, 8, 9)

That means we have 10 choices for Y and also 10 choices for Z

So, the number of possible ways are

$7\times10\times10=700$

But we know that the area code 666 has never been used.

So we need to subtract this one from the total.

$700-1=699$

Therefore, the total number of possible area codes is 699.
