Simplify this expression.

Answer:

x=0

Step-by-step explanation:

2^2 + x - 4 = 0

2^2 = 4

4+x-4 = 0

Combine like terms

x=0

[tex]\\ \sf\longmapsto \dfrac{215.7}{-4}[/tex]

[tex]\\ \sf\longmapsto \dfrac{216}{-4}[/tex]

[tex]\\ \sf\longmapsto -44[/tex]

Step-by-step explanation:

(-9)^2(2.7)-3/10(-2/5

= 81(2.7)-3/-2(2)

= 218.7-3/-4

= 215.7/-4

= -44

Answer:

2

Step-by-step explanation:

7x + 3 = 8x + 1

2 = x

these are geometry problems.

Since both cot(θ) and cos(θ) are positive, it follows that sin(θ) is also positive:

cot(θ) = cos(θ)/sin(θ) > 0   ===>   sin(θ) > 0

Recall the Pythagorean identity:

sin²(θ) + cos²(θ) = 1

Multiplying both sides by 1/sin²(θ) yields another form of the identity,

sin²(θ)/sin²(θ) + cos²(θ)/sin²(θ) = 1/sin²(θ)

1 + cot²(θ) = csc²(θ)

so that

csc(θ) = + √(1 + cot²(θ))

csc(θ) = √(1 + (3/2)²)

csc(θ) = √13/2

By definition of cosecant, we have

csc(θ) = 1/sin(θ)

so that

sin(θ) = 2/√13

Then using the Pythagorean identity once more, we have

cos(θ) = + √(1 - sin²(θ))

cos(θ) = √(1 - (2/√13)²)

cos(θ) = 3/√13

so that, by definition of secant,

sec(θ) = 1/cos(θ)

sec(θ) = √13/3

Answer:

[tex]2x + 5 < 19 \\ 2x < 19 - 5 \\ 2x < 14 \\ x < 7[/tex]

Answer:

The result can be shown in multiple forms.

Inequality Form:

−12< x < 7

Interval Notation:

(−12,7)

Step-by-step explanation:

first write |2x+5|<19 as a piece wise

2x+5≥0

To find the interval for the first piece, find where the inside of the absolute value is non-negative.

[tex]\frac{2x}{2}[/tex] ≥[tex]\frac{5}{2}[/tex] divide

x ≥−[tex]\frac{5}{2}[/tex] cancel common factor of 2

x ≥ −5/2.

To find the interval for the second piece, find where the inside of the absolute value is negative.

2x+5 < 0

substract by 5

2x < −5

divide by 2x

2x/2< −5/2

simplify to left side

x < −5 / 2

Simplify the right side.

x <  −5/2

In the piece where 2x+5 is negative, remove the absolute value and multiply by −1

− (2x+5) < 19

Write as a piecewise.

{2x+5 <19           x ≥ − 5/2

− (2x+5) < 19      x <− 5/2

Simplify −(2x+5)<19.

{2x+5<19       x≥−5/2

−2x−5<19      x<−5/2

Solve 2x+5 < 19 when x ≥ −5/2.

2x+5<19 for x.

Move all terms not containing x to the right side of the inequality.

2x < 14

divide by 2

x < 7

Find the intersection of x < 7 and x ≥−5/2.

−5/2 ≤x <7

Solve −2x−5 <19 when x <−5/2.

Move all terms not containing x to the right side of the inequality.

−2x<24

divide by -2

x>−12

Find the intersection of x > −12 and x <−5/2.

Find the union of the solutions.

−12 < x < 7

im pretty sure that the slope for both lines would be 2

Multiplying by 4 using the doubles strategy utilizes the fact that 4 is double of 2. Hence, 4 time any number is double of 2 times that number. Thus, given 4 x 8, it can be evaluated using the double strategy as follows 2 x 8 + 2 x 8 = 16 + 16 = 32

Step-by-step explanation:

Answer:

When you multiply two imaginary numbers, you are essentially multiplying them by itself or squaring them. If we recall, an imaginary number is the square root of -1. By squaring this number, you're eliminating the square root, ending up with -1 (aka a real number).

The area of the given figure that is mentioned is 64.

A square has congruent angles on each side. The square's area is thus equal to its square divided by its side length.

Let a represent the square's side length. The area of the square will be calculated as:

Area of the square = a² square units

The side provided is 8 ft

The area will be

= a²

= 8²

=64
