The angle measurements in the diagram are represented by the following expressions
Answer:
x = 8 , ∠ B = 70°
Step-by-step explanation:
∠ A and ∠ B are alternate exterior angles and are congruent, that s
8x + 6 = 4x + 38 ( subtract 4x from both sides )
4x + 6 = 38 ( subtract 6 from both sides )
4x = 32 ( divide both sides by 4 )
x = 8
Then
∠ B = 4x + 38 = 4(8) + 38 = 32 + 38 = 70°

The integral expression of the form ∫ f(x) · dg is equal to the composite expression f(x) · g(x) - ∫ g(x) df by applying integration by parts method. (Correct choice: A)
How to derive the rule of integration by parts
In this question we must derive a integration rule for the product of two functions that are integrable. The integration by parts method is inspired on the differentiation rule for the product of two differentiable functions, whose definition is shown below:
[tex]\frac{d}{dx} [f(x)\cdot g(x)] = f'(x) \cdot g(x) + f(x)\cdot g'(x)[/tex] (1)
If we integrate and used integral Calculus theorem on both sides of (1), then we have the following expression:
f(x) · g(x) = ∫ g(x) · df + ∫ f(x) · dg
∫ f(x) · dg = f(x) · g(x) - ∫ g(x) df
Therefore, the integral expression of the form ∫ f(x) · dg is equal to the composite expression f(x) · g(x) - ∫ g(x) df by applying integration by parts method. (Correct choice: A)

Answer:
12
Step-by-step explanation:
One property of a parallelogram is that diagonals bisect each other. This means that it "divides" each other in to two equal parts.
Since FK is 6, that means that KH is also 6.
Then you have to add both of those because FK and KH both make up the diagonal FH, FH is 12.

Identify the factors of x^2 - 4x – 21.
1. (x - 7)(x + 3)
2. (x + 7)(x - 3)
3. (x + 21)(x - 1)
4. (x - 21)(x + 1)
Answer:
1. (x - 7)(x + 3)
Step-by-step explanation:
x^2 - 4x – 21
We need two numbers that have a product of -21 and a sum of -4.
The numbers are -7 and 3 since -7 * 3 = -21, and -7 + 3 = -4
x^2 - 4x – 21 = (x - 7)(x + 3)
Answer: (x - 7)(x + 3)
Answer:
1
Step-by-step explanation:
X²-4x-21
-21×x²=-21x²
the factors of -4x and -21x² are -7x and 3x
x²-7x+3x-21
(x²-7x)+(3x-21)
X(x-7)+3(x-7)

Answer:
130°
Step-by-step explanation:
1. 59 + 71 (We do this because we want to find out their total to help us find out what the angle next to x is)
2. This should have given you 130°. Then, we will subtract 130 from 180 (180-130) (We do this because angles in a triangle add up to 180, so we want to find out what the single angle is).
3. This should have given you 50°. Since we know that angles on a straight line add up to 180°, we subtract 50 from 180 (180-50), and will eventually end up with 130°, so x=130°.
Let's look at the image and think about it for a second. We are given an exterior angle, and two opposite interior angles.
The sum of all angles in a triangle are equal to 180˚. If we look at angle ∠x , we notice something: it is a supplementary angle! ∠x + its supplementary angle is equivalent to 180. Conveniently enough, this supplementary angle is also an interior angle of the triangle.
You might be thinking, "Okay, so ∠x is a supplementary angle. Cool, so what?" Allow me to explain. Let's represent the unknown interior angle inside the triangle as 'n' (this isn't necessary to solve for x, but I'm just trying to prove how the solution works so you'll understand how to do these)
∠x + ∠n = 180˚ (These angles are supplementary)
∠n + 59˚ + 71˚ = 180˚ (The sum of interior angles of a triangle is 180˚)
If we isolate ∠n in both equations, then:
∠n = 180˚ - ∠x
∠n = 180˚ - 59˚ - 71˚
Since the right sides of both equations are equal, we can turn it into a single equation:
∠n = ∠n
180˚ - ∠x = 180˚ - 59˚ - 71˚
Isolate ∠x:
∠x = 59˚ + 71˚
So, what does this mean? This proof, essentially, establishes the fact that an exterior angle is equivalent to the sum of the two opposite interior angles. As you can see with the proof we made, ∠x is equal to the two opposite angles in the triangle, 59˚ and 71˚.
Now, let's get ourselves a definitive answer:
∠x = (59˚ + 71˚)
∠x = 130˚

Jackie bought a 3-pack of tubes of glue. She used 0.27 ounce of the glue from the 3-pack
and had 1.35 ounces left in total. Which describes a way to determine the number of ounces
sold in each tube of glue?
Divide 1.35 by 3 and then subtract 0.27 from the quotient.
Solve for in the equation 3 (x - 0.27) = 1.35.
Solve for x in the equation 3x - 0.27 = 1.35.
Subtract 0.27 from 1.35 and the divide the difference by 3.
Answer:
The answer is (A)
Step-by-step explanation:
:D
Answer:
Solve for in the equation 3 (x- 0.27)= 1.35
Step-by-step explanation:
First you look at a diagram and notice that you are moving forward so you are multiplying the 3 pack of tubes by the 0.27 ounce of glue to get your answer of 1.35

P is the incenter of △JKL. Find m∠JKP.
& can you please explain
Answer:
∠JKP = 35°
Step-by-step explanation:
since P is the incenter, then lines to incenter bisect the corner angles:
7x - 6 = 5x + 4
subtract 5 x from both sides of the equation:
2x - 6 = 4
add 6 to each side:
2x = 10
divide both sides by 2:
x = 5
∠KJP = 7(5) - 6 = 29°
∠LJP = 5(5) + 4 = 29°
then ∠KJL = 29° + 29° = 58°
∠KLJ = 26° + 26° = 52°
∠JKL = 180° - 58° - 52° = 70°
∠JKP = 1/2 ∠JKL = 1/2(70°) = 35°
there might be a more direct way about it but this was the least confusing way I know to explain it.
Find the surface area of the pyramid. The side lengths of the base are equal. Square pyramid with base edge of 12 centimeters, and a slant height measuring 17 centimeters, on a triangular face. The surface area is square centimeters.
Answer:
the surface area of the square pyramid is 576.66 cm^2
Step-by-step explanation:
The computation of the surface area of square pyramid is given below:
A = a^2 + 2a × √a^2 ÷ √4 + √h^2
where
a = 12 cm
h = 17 cm
Now put the value of a and h in the above formula
= 12^2 + 2(12) × √12^2 ÷ √4 + √17^2
= 576.66 cm^2
hence, the surface area of the square pyramid is 576.66 cm^2
