The expression x² − 17x − 60 can be factorized as (x + 3) (x- 20).
What is expression?An expression in math is a sentence with a minimum of two numbers/ variables and at least one math operation in it. Let us understand how to write expressions.
Constant: A constant is a fixed numerical value.Variable: A variable is a symbol that doesn't have a fixed value.Term: A term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.Coefficient: A coefficient is a number that is multiplied by a variable in an expression.Given:
x² − 17x − 60
Now, factorizing we get
x² − 20x + 3x − 60
= x(x − 20) + 3(x − 20)
= (x + 3) (x- 20)
Hence, the expression can be factorized as (x + 3) (x- 20).

Plz hurryThe center of circle Q has coordinates Q(6,-4) . If circle Q passes through R(14,2) , what is the length of its diameter?
Answer:
the diameter is twice the circle radius, or 20
Step-by-step explanation:
Recall that the radius is half the diameter <=> the diameter is twice the radius. In this problem we need to find the radius first, then multiply it by 2 to obtain the diameter.
We need to determine the distance between the center of the circle Q(6, -4) and the point R(14, 2) on the circle.
The Pythagorean Theorem applies here. Going from Q to R, x changes from 6 to 14, or 8 units, which is the horizontal leg of a right triangle, and y changes from -4 to 2, or 6 units. Thus, according to the Pythagorean Theorem, the length of the hypotenuse of this triangle is
r = √(6² + 8²) = √100 = 10
and so the diameter is twice that, or 20.
How many deli sandwiches did she make?
Please help me.
Answer: 6 sandwiches
Step-by-step explanation:
To get the amount of roast beef that Marissa used you would have to subtract 2 3/4 from 5...which is 2.25 pounds of beef that she used.
Then you would divide 2.25 by 3/8 which is 6... meaning Marisa made 6 sandwiches!

у
A. -1 < x < 6
B. -1 < y = 6
C. -2 < x < 5
D. -1 3y = 6
Answer:
Option A is the correct answer
Step-by-step explanation:
[tex] - 1 \leqslant x \leqslant 6[/tex]
The domain of the function is -1 ≤ x ≤ 6 or x ∈ [-1, 6] option (A) -1 ≤ x ≤ 6 is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a given a graph of a function in the picture.
As we can see, the at point x = -1 graph starts, and it has dark dot which means function values exist at x = -1.
Similarly, at x = 6 the function value exist.
The domain of the function:
-1 ≤ x ≤ 6
Thus, the domain of the function is -1 ≤ x ≤ 6 or x ∈ [-1, 6] option (A) -1 ≤ x ≤ 6 is correct.

A 5m ladder reaches 4.2m up a wall. What angle does the ladder make with the wall
Answer:
57.14°
Step-by-step explanation:
A 5m ladder reaches 4.2m up a wall. What angle does the ladder make with the wall?
We solve the above question using the Trigonometric function of Sine
= sin theta = Opposite/Hypotenuse
Opposite = Length of the wall = 4.2m
Hypotenuse = Length of the ladder = 5m
Theta = Angle formed = x
Hence,
sin x = 4.2m/5m
x = arc sin(4.2m/5m)
x = arc sin(0.84)
x = 57.140119621°
Approximately = 57.14°

9. Bianca is hosting a dinner party for 10 people. The main course's recipe states
that 400 g of sausage and 500 g of dry pasta is enough for four people.
a) How much sausage will she need?
b) How much pasta will she need?
Answer:
a) 1000 grams
b) 1250 grams
Step-by-step explanation:
Find out how much grams of sausage and dry pasta she needs for each person.
4 people = 400 g
1 person = 400 ÷ 4 = 100 g (sausage)
4 people = 500 g
1 person = 500 ÷ 4 = 125 g (dry pasta)
Find out how much grams of sausage and dry pasta is needed for 10 people.
10 person = 100 x 10 = 1000g (sausage)
10 person = 125 x 10 = 1250g (dry pasta)

Triangle ABC is an acute triangle. Two sides measure 5 and 7. What is the range of possible values for its third side?
Answer:
the desired range is 2 < t < 12.
Step-by-step explanation:
If the third side is 12 (the sum of 5 and 7), we don't really have a triangle, since the 5-unit and 7-unit sides add up to 12 and lie on the third side (of length 12).
Since triangle ABC is acute, all its angles are between 0 and 90 degrees. So the third side can be 12 but not greater. The smallest possible length of the third side is 2, since 5 + 2 = 7.
Thus, the desired range is 2 < t < 12.
