Answer:
D. 2x² + 10x - 2
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
Length = x² + 3x - 2
Width = 2x + 1
Perimeter = 2(x² + 3x - 2 + 2x + 1)
Perimeter = 2(x² + 5x - 1)
Perimeter = 2(x²) + 2(5x) - 2(1)
Perimeter = 2x² + 10x - 2

What are the values of a and b?
Answer:
D
Step-by-step explanation:
These two triangles are similar triangles. The two angles marked are the same and the two angles at the intersection where you see the square are also the same, making it clear that the last angle must be the same as well.
Therefore,
length 8 from the top triangle is similar to length 6 on the bottom triangle,
length 10 from the top is similar to b on the bottom triangle,
length 6 from the top is similar to a on the bottom.
To find the ratio of similarity, you would compare the length 8 to length 6, and divide them. 8/6 = 1.33333
Now that you've found the proportionality constant, you divide the other two lengths on the top triangle with the constant to get b and a.
b = 10/1.3333 = 7.5
a = 6/1.3333 = 4.5
Therefore, the answer is D: a = 9/2, b = 15/2.

The measure of base angle of the isosceles right angle triangle is 45°.
What is a right angle triangle?A right-angled triangle is a triangle, that has one of its interior angles equal to 90 degrees or any angle is a right angle.
Given that,
Triangle ABC is an isosceles right angle triangle.
In an isosceles triangle, two sides are equal and corresponding angles are equal.
Let the corresponding angles are α and α.
Since, one angle of right angle isosceles triangle is 90°.
Also, the sum of angles of triangle is 180°
Implies that,
α + α + 90 = 180
2α = 180 - 90
2α = 90
α = 45
The required value of angle α is 45°

A dog is pulling a 15kg sled to the right with a force of 15N. A rhino is pulling the same sled to the left with a force of 42N. There is a frictional force of 5.0N acting on the sled.
Which direction is the friction acting?
What is the Net Force on the sled?
What is the acceleration of the sled?
What is the coefficient of friction on the sled?
9514 1404 393
Answer:
to the right22 N22/15 ≈ 1.467 m/s²5/147 ≈ 0.034Step-by-step explanation:
a) Friction opposes motion, so is in the opposite direction of the net force on the sled. Taking "left" to be "positive", the two animals are applying a net force of +42 N -15 N = 27 N. That is to the left, so the friction force is to the right.
__
b) The total of forces applied by the animals and friction is ...
27 N -5 N = 22 N . . . to the left
__
c) Acceleration can be found from the relation ...
a = F/m . . . . 'm' is mass
a = (22 N)/(15 kg) = 22/15 m/s² . . . . 'm' is meters
__
d) The coefficient of friction is the ratio of friction force to the normal force on the surface producing the friction. Here, that normal force is the force due to gravity acting on the 15 kg mass of the sled.
coefficient of friction = (5 N)/(9.8 m/s²·15 kg) = 5/147
coefficient of friction ≈ 0.034
Answer:
1. to the right
2. 22 N
3. 22/15 ≈ 1.467 m/s²
4. 5/147 ≈ 0.034

Problem:
Craig earns extra money as a lifeguard. He earns $37 for 4 hours and $64.75 for 7 hours.
Answer:
The answer is: y = 9.25x
Step-by-step explanation:
Let the equation for the proportionality relation is y = mx .......... (1), where y represents the money that Craig earns for a duty of x hours.
Here, m is the constant of proportionality and we have to find its value.
Given that Craig earns $37 for 4 hours duty.
So, from equation (1), we have 37 = 4m, ⇒ m = 9.25
Therefore, the equation becomes y = 9.25x. (Answer)
How to graph y=12-6x
Answer:
The answer will be listed below.
Step-by-step explanation:
This equation is in y=mx+b form, so to graph this equation, take the y-intercept which would be 12. Go on your graph and make twelve on the y-axis (you can go by two's or even six's). Then take your slope which would be -6 and use rise of run which would be down 6, since it's negative, and to the right one. Keep repeating this process until you ran out of space. Draw a line between the points and you have graphed a line.

Peter collected 171 marbles but lost 3/4 of them on his way home through of hole in his bag when he arrived at home now many marbles did Peter have left?
The number of marbles Peter had when he arrived home was 43 marbles
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
The number of marbles Peter had on his way home = 171
The amount of marbles he lost on his way home = ( 3/4 ) th
Now , the amount of marbles Peter have left = 1 - amount of marbles he lost on his way home
The amount of marbles Peter have left = 1 - 3/4
= ( 1 / 4) th
So , The number of marbles Peter had left when he arrived home is =
Amount of marbles Peter have left x Number of marbles Peter had
The number of marbles Peter had left when he arrived home is = (1/4) x 171
= 171 / 4
= 42.75
≈ 43 marbles
Hence , the number of marbles Peter had left when he reached home is 43
