Answer:
C
Step-by-step explanation:
A patio=(x+15)*(x+10)
A bench=5*1=5
A painted=A patio-A bench
A painted=(x+15)*(x+10)-5
thus, the answer is C
The painted area is [tex]a=(x+15)(x+10)-5[/tex]. So, option C is correct.
Important information:
Length of rectangular patio is (x+15).Width of rectangular patio is (x+10).Length of bench is 5.Width of bench is 1.Area of rectangle:Area of a rectangle is:
[tex]A=Length \times Width[/tex]
Area of rectangular patio is:
[tex]A_1=(x+15)(x+10)[/tex]
Area of bench is:
[tex]A_2=5\times 1[/tex]
[tex]A_2=5[/tex]
The painting area is:
[tex]a=A_1-A_2[/tex]
[tex]a=(x+15)(x+10)-5[/tex]
Therefore, the correct option is C.

Steven spent 2 hours and 30 minutes to attend 3 classes. If it took him the same amount of time to attend each class, how long would it take him to attend 5 classes?
Answer:
about 4.17 hours
Step-by-step explanation:
To solve the time for each class, you do 2.5 hours divided by 3. Then you take this value and multiply by 5 since there are 5 classes. After you do this, you should get 4.17 hours roughly.

A parallelogram has rotational symmetry and triangle has no points of symmetry. Therefore, option 4 and 5 are correct answers.
What is a point symmetry?Point Symmetry is when every part has a matching part the same distance from the central point but in the opposite direction. It looks the same when viewed from opposite directions (180° rotation).
1) A figure has point symmetry, if it has a rotational symmetry of 180 degrees.
2) An object is said to possess rotational symmetry if it takes the same shape before and after its rotation along its point of rotation.
3) In order for a figure to have reflectional symmetry, there needs to be at least one axis such that when the the figure "folds" over that axis it maps into itself.
4) A parallelogram has rotational symmetry. A parallelogram does not have reflectional symmetry.
So, all parallelograms have point symmetry.
5) Triangle has no points of symmetry, because there is no up and down shapes in triangle
A parallelogram has rotational symmetry and triangle has no points of symmetry. Therefore, option 4 and 5 are correct answers.

Step-by-step explanation:
From the question, Sara is having a dinner party for four friends and she needs to reduce the serving size of the meatloaf recipe. Sara used the equation x/4=5 . To get the number of servings the recipe originally made, we have to find the value of x.
x/4 = 5
x = 4 × 5
x = 20
This means that the recipe that was used originally made 20 servings.

Step-by-step explanation:
[tex]\sqrt{64}[/tex]=±8
Answer:
B. -8 and 8
Step-by-step explanation:
To solve this equation, we need to get x by itself. To do this, perform the opposite of what is being done to the equation. Keep in mind everything must be done to both sides of the equation.
x^2=64
x is being squared. The opposite of being squared is taking the square root. Take the square root of both sides.
√x^2=√64
The exponent and square root on the left will cancel, and x will be left by itself.
x=√64
x=±8
The solutions of the equation are x=8 and x= -8
Therefore, the answer is B. -8, 8
The expression 2(a+b)=−8.1 for certain values of a and b. Find the value of the following expressions for the same values of a and b: −0.5(a+b)
Answer:
Interpreting as: 2(a+b)=-8.1
Input:
2 (a + b) = -8.1
In Given the expression
2( a + b) = 8.1 ..........................(1)
now divide both sides of the first equation by 2 ,
2 (a + b) /2 = 8.1 /2
(a + b) = 4.05
expression -0.5(a + b) ................(2)
simply put the value of (a + b) in (2),
- 0. 5( 4.05) = -0.5 * 4.05
= 2.025
Value of expression is 2.025.

Answer:
48cm^2
Step-by-step explanation:
We are given some of the measurements of the piece of cardboard.
First, let's find the lengths of all the sides of the cardboard, as it will be easier to then find the area.
Going in clockwise order, from top to bottom, the dimensions are:
4cm, 7cm, 6cm, 2cm, 10cm, 9cm.
Now, we can easily find the area by using the formula BH=Area. Let's split the cardboard into sections that will be easier to find the area of. Say we split it in two, rather like a sneaker with the person wearing a sock showing at the ankle (I have strange explanations, I know).
To find the top part (the sock part) we can multiply 4 by 7 to get 28.
To find the shoe part, we can multiply 10 by 2 to get 20.
Finally, add these areas together to get the total area.
20 + 28 = 48
Another way to do this (if my sock and sneaker explanation was too chaotic for you) would be to imagine that the cardboard piece were an entire rectangle (ignore that chunk that has been cut out).
The area of that would be 90, from 9 by 10 as the side lengths. Then, from earlier, we know that the width and length of the chunk that has been cut out is 6 and 7, so the area that will be cut out is 42.
Subtract 42 from 90 to get 48.
