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:(x-7)(X+3)

Explanation:
Since the line is straight, line segment for me. Hope it helps!
Answer:
A line
Step-by-step explanation:
Roughly, we can say that a line is an infinitely thin, infinitely long collection of points extending in two opposite directions. When we draw lines in geometry, we use an arrow at each end to show that it extends infinitely.

leg b =

hypotenuse c =

Right triangle? Yes or No.
how would you solve this?!?
Answer:
The answer would be sin A
Step-by-step explanation:
The answer is Sin A because to find sin the equation is opposite/ hypotenuse
and if you do Sin C the answer would be[tex]\frac{4\sqrt{6}}{11}[/tex] and that does not equal [tex]\frac{5}{11}[/tex].

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
Please find the area of the shaded region. Assume the outside shape is a square. 30 m 15 m 45 m
Answer:
Shaded region is the difference of the areas of the parallelogram and the square:
A = 45*30 - 15² = 1125 m²Answer:
area of shaded region=1125m²
Solution given:
base of parallelogram [b]=45m
height of parallelogram [h]=30m
length of square [l]=15m
we have
Area of shaded region =Area of {parallelogram -square]
=b×h-l²=45×30-15²=1125m²

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

Help me with this for brainiest
Answer:
11) 2 x 3.14 x (19/2) > (we want to use the radius)
2 x 3.14 x 9.5 = 59.66
12) 2 x 3.14 x (11/2) > (we want to use the radius)
2 x 3.14 x 5.5 = 34.54
34.54/2 + 11 = 28.27 >(becuase it is only a semicircle)
the plus 11 is the diameter, because the cirlce is cut in half

Concept 9.3: Find the value of x in the circle.
Answer:
x=4.5
Step-by-step explanation:
MAB=MBC
AB=BC
3x+2=5x-7
7+2=5x-3x
9=2x
x=9/2
x=4.5
hope it helps..
have a great day!!
Answer:
x = 4.5
Step-by-step explanation:
here's your solution
=> AB = BC. ( both arc are equal )
=> 3x + 2 = 5x - 7
=> 3x - 5x = - 7 - 2
=> - 2x = - 9
=> x = 9/2
=> x = 4.5
hope it helps

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.
Answer:
12

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.

Step-by-step explanation:
What are the steps to solving the inequality 3b + 8 2 14?
O Subtract 8 from both sides of the inequality. Divide both sides of the inequality by 3.
O Subtract 8 from both sides of the inequality. Change the direction of the inequality. Divide both sides of the
inequality by 3.
O Divide both sides of the inequality by 3. Subtract 8 from both sides of the inequality.
O Divide both sides of the inequality by 3. Change the direction of the inequality. Subtract 8 from both sides of the
inequality.
Answer:
Subtract 8 from both sides of the inequality. Divide both sides of the inequality by 3.
Step-by-step explain
The given inequality is 3b + 8 ≥ 14
We need to solve the given inequality
Step 1.
Subtract 8 to the both sides of the inequality
3b + 8 - 8 ≥ 14 -8
3b ≥ 6
Dividing both sides by 3
b ≥ 2
The value of b is greater than and equal to 2.
the correct answer is a.
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°
