Answer: 15.
Step-by-step explanation: To find the slope, you need to use rise/run which is done below if you need a visual look at what I'm saying. Before we use rise/run, we need two points on the line. We'll use (2, 80), and (6, 140). We need to go 60 up and 4 to the right to make the points meet. Going up or down is the rise and left or right is the run. Our rise/run is 60/4 or 15 when you divide. Therefore, 15 is your slope for this equation of a line.

Answer:
C) [tex]6r^2-9r-6[/tex]
Step-by-step explanation:
Open the parentheses, you get:
[tex]-3r^2-2r-4+9r^2-7r-2[/tex]
Then combine like terms:
[tex]-3r^2+9r^2=6r^2\\-2r-7r=-9r\\-4-2=-6\\[/tex]
Then right as a polynomial:
[tex]6r^2-9r-6[/tex]
So the answer would be C)
Answer:
6r² - 9r - 6
Step-by-step explanation:
(-3r² - 2r - 4) - (-9r² + 7r + 2)
Multiply to remove the parenthesis:
(-3r² - 2r - 4) - (-9r² + 7r + 2)
1(-3r² - 2r - 4) - 1(-9r² + 7r + 2)
1(-3r²) +1(-2r) + 1(-4) + -1(-9r²) + -1(7r) + -1(2) <== remember that multiplying 2 negatives, makes a positive
-3r² - 2r - 4 + 9r² - 7r - 2
Combine any like terms:
-3r² - 2r - 4 + 9r² - 7r - 2
6r² - 9r - 6 <== make sure that your answer is in Standard form (in decreasing degrees)

Maren is completing a wood working project. She needs 90 feet of wood. She has 8 pieces of wood that are each 6.2 feet long in her garage. How much more wood will she need to complete the wood working project?
Answer:
She needs 40.4 feet of wood.
Step-by-step explanation:
➾ She had 8 pieces of wood that are 6.2 feet each, so total length of wood she had = 8×6.2
= 49.6feet.
➾She needs total 90feet. of wood and she had already 49.6 feet of wood.
So, now wood she needed = 90-49.6
= 40.4feet.

Hope it helps you:)
Answer:
She needs 40.4 feet of wood
Step-by-step explanation:
Given :-
Maren has 8 piece of wood which are 6.2 feet longShe needs total 90 feet of woodTo find:-
How much wood will she need moreSolution:-
Amount of wood she needs more :-
Wood she wanted to complete project — Wood she already have
by putting the value ,
90 feet — 8 × 6.2 feet
= 40.4 feet

Answer:
Area of square: 9/16 m²
Step-by-step explanation:
We are given:
Side length of square: 3/4 metersThe area of the square is the side multiplied by the same side. Therefore,
⇒ Area of square: (3/4) × (3/4)⇒ Area of square: (3/4)²Using the exponents property, [(a/b)² = (a²/b²)]:
⇒ Area of square: (3²/4²)⇒ Area of square: (9/16) m²Therefore, the area of the square is 9/16 m².
Answer:
[tex]\huge\boxed{\bf{Area_{square} = \frac{9}{16}m^2}}[/tex]

Slide length of square = [tex]\frac{3}{4}[/tex]m.To Find : -
Area of squareAns : -
$\sf \to Area_{square} = (side\:length)^2$

What is the Area of a Circle?Area of a circle = πr², where r is its radius.
What is the Area of a Rectangle?Area of a rectangle = length × width
What is the Area of a Triangle?Where b is the height and b is the base length, area of triangle = 1/2bh.
What is the Area of a Square?Area = s², where s is the side length.
1. Area of the figure = area of square + area of rectangle = s² + length × width
Area of the figure = 3² + 6 × 3 = 27 ft²
2. Area of the figure = area of circle + area of rectangle = πr² + length × width
Area of the figure = π(7²) + 24 × 16 = 537.9 ft²
3. Area of the figure = area of smaller rectangle + area of bigger rectangle
Area = 12 × 12 + 20 × 12 = 384 yd²
4. Area of the figure = area of 1/2circle + area of triangle = 1/2πr² + 1/2bh
Area of the figure = 1/2π(8²) + 1/2(8)(17) = 168.5 cm²
5. Area of the figure = area of rectangle + area of triangle = (l)(b) + 1/2bh
Area of the figure = (10)(7.5) + 1/2(7.5)(5) = 96.3 m²
6. Area of the figure = area of 1/2circle + area of triangle = 1/2πr² + 1/2bh
Area of the figure = 1/2π(4²) + 1/2(8)(12) = 73.1 cm²
7. Area of the figure = area of 1/2circle + area of rectangle = 1/2πr² + 1/2bh
Area of the figure = 1/2π(10²) + (20)(10) = 357.1 in.²
8. Area of the figure = area of rectangle + area of triangle = (l)(b) + 1/2bh
Area of the figure = (35)(21) + 1/2(28)(21) = 1,029 m²
9. Area of the figure = area of square + area of rectangle = s² + length × width
Area of the figure = 18² + 21 × 20 = 744 in.²

The quotient of the expression in form of a + bi is 9/13 - 20/13i
Rationalizing complex expressionsGiven the following expressions
1+6i/-3+2i
Rationalizing the given rational complex number, we will have;
= 1+6i/-3+2i * -3-2i/-3-2i
= (1+6i)(-3-2i)/9+4
= -3-2i-18i-12i²/13

Find the next two numbers in the sequence 5,2,-1,…
Answer:
The answer is (-4) and (-7).
Step-by-step explanation:
Given;a₁ = 5a₂ = 2a₃ = (-1)To Find;a₄ = ?a₅ = ?Formula;aₙ = a + (n – 1) × dNow, for common difference (d)
d = a₂ – a₁ = 2 – 5 = -3
d = a₃ – a₂ = (-1) – 2 = -3
Here, common difference is same everywhere.
So, for fourth term or n = 4
aₙ = a + (n – 1) × d
a₄ = 5 + (4 – 1) × (-3)
a₄ = 5 + 3 × (-3)
a₄ = 5 – 9
a₄ = -4
Then, for fifth term or n = 5
a₅ = 5 + (5 – 1) × (-3)
a₅ = 5 + 4 × (-3)
a₅ = 5 – 12
a₅ = -7
Thus, The fourth term is (-4) and fifth term is (-7).
