Answer:

x=1

Step-by-step explanation:

First you would do the parentheses.

So, 4 x X= 4x

4x2=8

4x+8=2x+10

subtract 2x on both sides

2x+8=10

subtract 8 from both sides

2x=2

x=1

Answer:

Step-bvery nonnegative real number x has a unique nonnegative square root, called the principal square root, which is denoted by √x, where the symbol √ is called the radical sign or radix. For example, the principal square root of 9 is 3, which is denoted by √9 = 3, because 32 = 3 ⋅ 3 = 9 and 3 is nonnegative.y-step explanation:

Answer:

27

Step-by-step explanation:

9*3=27

since it's always 3 times the amount of the left side we would just multiply 9 by 3

The required value of x would be 27 in the given ratio 1:3 = 9:x​.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

The ratio is given in the question as follows:

1:3 = 9:x​

We have to determine the value of x in the given ratio.

As per the question, we have

1:3 = 9:x​

⇒ 1/3 = 9/x

Apply the cross-multiplication,

⇒ x = (3) × (9)

Apply the multiplication operation, and we get

⇒ x = 27

Therefore, the required value of x would be 27.

Answer:

top right

Step-by-step explanation:

Answer:

40. 3*2 is equal to 6 so 20*2 equals 40

The value of the missing number in the equation is 40.

Given the equation in the question:

20/3 = ?/6

Let x represent the missing number:
Hence:

20/3 = x/6

To solve for x, we cross-multiply and simplify:

20/3 = x/6

Cross multiplying, we get:

3 × x = 20 × 6

Multiply 3 and x:

3x = 20 × 6

Multiply 20 and 6:

3x = 120
Divide both sides by 3:

x = 120/3

x = 40

Therefore, the value of x is 40.

Answer: Yes

Step-by-step explanation: Because of the gravity of the earth

The tangent line to f(x) at x = c has slope equal to the derivative at c, or f'(c).

We have

f(x) = 3 - 2 x + 7 x²

so that

f'(x) = -2 + 14 x

The slope is 5 for

-2 + 14 x = 5   ==>   14 x = 7   ==>   x = 1/2

Now, f (1/2) = 15/4, so the tangent line has equation

y - 15/4 = 5 (x - 1/2)   ==>   y = 5 x + 5/4

Answer: - 3/4

Step-by-step explanation:

It fits

So let's narrow it down.

Less than 0, greater than -4

That gives us three whole numbers, -3, -2, and -1.

So that does not really narrow it down, because all of those aren't integers and are rational.

Answer:

  use the definition of isosceles to claim congruent sides (or angles), and use the shared side and the fact that angles at C are 90°. Claim HL or AAS congruence.

Step-by-step explanation:

Approach to the problem

Of course, AC is congruent to itself. AC ⊥ BD means ∠ACB ≅ ∠ACD ≅ 90°. Then the fact that the larger triangle is isosceles lets you claim angle B = angle D, or AB = AD (or both).

If you use the congruence of angles, you can claim AAS congruence for the triangles. If you use the congruence of sides, you can claim HL congruence for the right triangles.

Specifics

1. ∠ACB ≅ ∠ACD (= 90°) . . . . definition of perpendicular

2. AB ≅ AD . . . . definition of isosceles triangle

3. AC ≅ AC . . . . reflexive property of congruence

4. ∆BAC ≅ ∆DAC . . . . HL congruence theorem

Answer:

n=2

Step-by-step explanation:

subtract 4n - 2n

2n=4

divide by 2 to get rid of the two on the n side

n=2

The value of n in the equation 4n - 2n = 4 is n = 2.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

To find the value of n in the equation 4n - 2n = 4, combine like terms on the left side of the equation:

4n - 2n = 4

(4 - 2)n = 4

2n = 4

To isolate n, we divide both sides of the equation by 2:

2n/2 = 4/2

n = 2

Therefore, the value of n in the equation 4n - 2n = 4 is n = 2.
