The second choice
Step-by-step explanation:
Perimeter is calculated by adding the length and width but multiplied by 2. You add 3.2 and 1.5 and get 4.7. Multiply 4.7 by 2 would give you 9.4.
Area is multiplying the length and width. 3.2 multiplied by 1.5 would be 4.8

Answers
Answer:
-5n = 1 ⇒ n = -¹/₅ n+15 = (-10) ⇒ n = 25 n/5 = -1/5 ⇒ n = -1 n-13= -12 ⇒ n = 1Step-by-step explanation:
-5n = 1
÷(-5) ÷(-5)
n = -¹/₅
n + 15 = (-10)
-15 -15
n = -25
n/5 = -1/5
×5 ×5
n = -1
n - 13 = -12
+13 +13
n = 1
Answer:
-5n = 1 : n = -¹/₅
n+15 = (-10): n = -25
n/5 = -1/5 : n = -1
n-13= -12: n = 1

given:
A cylinder has a circular base radius 14cm and height of 10cm.
find:
the total surface area of the cylinder. [take pie 22/7] *
solution:
surface area (As) = 2πrh + 2πr²
where r = 14 cm; h = 10 cm; π = 22/7
plugin values into the formula:
As = 2 (22/7) 14 (10) + 2 (22/7) 14²
As = 880 + 1232
As = 2112 cm²

If point Q is between endpoints P and R on a segment, PQ = 4x - 12, QR = 2x + 7, and PR = 31, then find the value of x.
Answers
Answer:
x = 6
Step-by-step explanation:
Here it's sayin that Q is a point in between the end-points P & R. If we join P & R , it forms a line segment & Q is in the line segment PR. Hence PQ & QR are also line segments which combine to form line segment PR. So ,
PR = PQ + QR
Putting the given values of PQ ,QR & PR
=> 4x - 12 + 2x + 7 = 31
=> 6x - 5 = 31
=> 6x = 31 + 5
= 36
=> x = 36/6 = 6

Robert had $58.62 in his bank account. He got paid $142.76. He then bought a new jacket for $63.76. He also bought 2 new movies for $6.99 each. He then babysat for his sister and was paid $12. How much money does Robert have now?
Answers
Robert then decides to buy a new jacket that costs $63.76 which means he made a withdrawal from his account of $63.76
So you would now subtract the total in his bank account from the cost of the new jacket. This leaves him with $137.62 left in his bank account.
Next Robert bought two new movies, which each cost $6.99 and so because he bought two movies, you multiple $6.99 by two. This comes out to $13.98 which is the amount Robert paired to purchase the two new movies. Robert withdrew the $13.98 from his bank account, leaving him with $123.64 left in his bank account.
Finally, Robert is paid $12 for babysitting his younger sister. He adds this to his bank account, which means his bank account total is $135.64
This means that Robert now has $135.64 in his bank account.

The product of a number and 7 decreased by 2
Answers
Answer:
(x× 7) -2
Step-by-step explanation:
(x× 7) -2
product of # = x
and 7 means to multiply
decreased by two means -2
Answer:
the product of a number and seven decreased by two is 7x-2
Step-by-step explanation:
a "product" is the answer to a multiplication problem. instead of writing a multiplication symbol (x) we can simply put the variable next to the number it is being multiplied to. (7x) so, a number (which can be written as any letter, since we don't know the exact number- it's a variable.) 7x decreased by 2 means subtracting. so, we get 7x-2.

3x + 2y=11 // 2x - 2y = 14 solve I substitution method
Answers
Hey there! I'm happy to help!
To solve by substitution, rearrange one of the equations for one of the variables.
3x+2y=11
Subtract 2y from both sides.
3x=11-2y
Divide both sides by 3.
x=11/3-2/3y
Now we plug this value of x into the second equation to solve for y.
2(11/3-2/3y)-2y=14
We use distributive property to undo the parentheses.
22/3-4/3y-2y=14
We combine like terms.
22/3-10/3y=14
We subtract 22/3 from both sides.
-10/3y=20/3
Divide both sides by -10/3.
y=-2
We plug this value into one of the equations to solve for x.
3x+2(-2)=11
3x-4=11
Add 4 to both sides.
3x=15
Divide both sides by 3.
x=5
So, the solution is x=5 and y=-2 or (5,-2).

Explanation:
First, your gonna wanna subtract the amount she had before, minus how much she has now.
23
-17
——
6
Next, you should’ve got a difference of 6. Your gonna wanna divide that by two because remember she said she wanted TWO pencils.
6÷2= 3
Lastly, based on the answer you got you should know that it...
It cost $3 for each pencil.

a high school football player is practicing his frield goals kicks. The equation h=-9t²+45t where t is the number of seconds gone by and h is the height of the ball in feet. how long does it take for the ball to hit the ground
Answers
h = -9t^2 + 45t
First, let's factor the equation.
h = -9t(t - 5)
Let's set both terms equal to zero.
-9t = 0
Divide both sides by -9
t = 0
t - 5 = 0
Add 5 to both sides.
t = 5
We know that it took more than 0 second sto hit the ground, therefore, the only answer that makes sense is t = 5
It took 5 seconds for the football to hit the ground.
The definition of parallel lines requires the undefined terms line and plane, while the definition of perpendicular lines requires the undefined terms of line and point. What characteristics of these geometric figures create the different requirements?
Answers
Answer:
Parallel lines requires the terms line and plane because line and plane that are parallel cannot cross each other therefore they will never make a point of intersection. The characteristics of that parallel lines consists of lines and planes. Perpendicular lines requires the terms line and point because whenever two lines intersect, it creates a point and whenever two planes intersect, it creates a line. The characteristics of that perpendicular lines are points and lines.
The characteristics of the geometric figures that create the different requirements are;
Parallel lines are lines on the same plane and that are equidistant from each otherPerpendicular lines are lines that form a 90 degree angle at the point of their intersection.Reasons:
The characteristics of parallel lines are;
The shortest distance between the lines that are parallel is the same at all points along the lines.The lines are on the same plane.As the plane is extended indefinitely, the lines do not intersect.The characteristics of perpendicular lines are;
Perpendicular lines are lines that intersect at a point.Where two lines are perpendicular, the slope of one line is the negative reciprocal of the other, such that the product of the slopes of two lines that are perpendicular is -1.The angle formed at the intersection of perpendicular lines is 90°.An horizontal and a vertical line on the same plane are perpendicular to each other.Therefore, the characteristics of the geometric figures that create the different requirements are;
Parallel lines are lines on the same plane.Perpendicular lines are lines that form a 90 degree angle at the point of their intersection.Learn more about parallel and perpendicular lines here:
