Answer and explanation:
The surface area of a solid is the sum of the areas of all faces of the solid. The surface area of a cube is calculated using the formula 6a² since a cube has 6 faces in total likewise a cuboid.
We can say the rectangular solid is a cuboid and to find the surface area of the cuboid we add up the surface area of all 16 cubes
Surface area is therefore 16×6a²
P=-30h+74 The variable h represents the number of hours he has spent reading, the variable p represents the number of pages left to read. How many hours of reading will Ethan have to do in order to have 14 pages left to read?
Answer: Ethan will have to spend 2 hours reading if 14 pages are left to read
Step-by-step explanation:
Given the equation
P=-30h+74
where p =number of pages left to read and
h= the number of hours he has spent reading
Therefore , if Ethan has 14 pages left to read, then the number of hours Ethan will have to read will be
P=-30h+74
14= -30h + 74
30h= 74-14
30h= 60
h = 60/30
h =2 hours
Ethan will have to spend 2 hours reading if 14 pages are left to read

Margo added three multi-digit decimal numbers. The first number was 5.19. The second number was 10 times the first number. The third number was 10 times the second number. What was the sum?
Answer: 576.09
Step-by-step explanation:
First number = 5.19.
The second number was 10 times the first number which will be:
= 5.19 × 10
= 51.9
The third number was 10 times the second number. Thus will be:
= 51.9 × 10
= 519
The sum of the numbers will be:
= 1st number + 2nd number + 3rd number
= 5.19 + 51.9 + 519
= 576.09

Use the Distributive Property to solve the equation.
- 8(x + 7) = 16
Apply the Distributive Property and simplify.
- 8(x + 7) = 16
- 8x + = 16
Answer:
x= - 9
Step-by-step explanation:
- 8(x +7) = 16-8x - 56 = 16 -8x = 16 + 56-8x = 72x = 72 ÷ (-8) x = -9Hey there!
Use the Distributive Property and simplify:
-8(x+7)=16
-8x-56=16
Notice we write -8 right next to x.
Add 56 to both sides:
-8x=16+56
-8x=72
Divide both sides by -8:
x=-9
Hope everything is clear.

Isabella and her cousin Rodrigo have the same birthday but isabella is 15 years older than Rodrigo the equation y= x + 15 represents isabella's age y, when Rodrigo is x years old what is the answer?.
Answer:
The answer is below
Step-by-step explanation:
Isabella and her cousin rodrigo have the same birthday, but isabella is 15 years older than rodrigo is x years old. which table of value shows this relationship
Solution:
Let x represent Rodrigo's age and let y represent Isabella's age. Since Isabella is 15 years older than Rodrigo, hence her age is given by the equation:
y = x + 15
You can use a table to represent the relationship between their ages. Let us find the corresponding Isabella age for the following Rodrigo age.
Rodrigo: 10 20 30
Isabella: 25 35 45
When x = 10: y = x + 15 = 10 + 15 = 25
When x = 20: y = x + 15 = 20 + 15 = 35
When x = 30: y = x + 15 = 30 + 15 = 45
Anais bought 4 1/2 yards of ribbon. She had 3 feet 8 inches of ribbon left after trimming some curtains. How many inches of ribbon did anais use to trim the curtains
Answer:
First convert all numbers into inches since that is the answer being solved for.
1 yard =36 inches
4.5 x 36 = 1,620 inches
1 foot = 12 inches
3 x 12 = 36 inches
36 + 8 = 44 inches
Now take 1,620 inches (starting ribbon measure) and subtract 44 inches (what was left over) to get the inches used to trim curtains.
1,620 inches - 44inches =
1,576 inches were used to trim the curtains.

Answer:
x = 60
Step-by-step explanation:
subtract 7 from both sides:
7 + x - 7 = 2x - 53 - 7
Simplify:
x = 2x - 60
Subtract 2x from both sides:
x - 2x = 2x - 60 - 2x
Simplify:
-x = -60
Divide by -1=
-x/-1 = -60/1

What does the quadratic function
f(x) = x2 - 6x + 8 look like when it is
rewritten in the form f(x) = a(x − p)2 +q?
Answer:
f(x) = (x -3)^2 - 1
Step-by-step explanation:
f(x) = x^2 - 6x + 8
a = 1, b = -6 and c = 8
So we are finding half of the b equation (ignore the negative sign)
Half of 6 is 3, so we are going to square 3 (3^2 = 9) and add 9 to the left side and subtract 9 to the right side
(x) = (x^2 - 6x + 9) + (8 - 9)
You can tell the polynomial is a perfect square, so we will have to factor it using the perfect square method
(x^2 - 6x + 9)
square toot of x^2 is x and square root of 9 is 3 and the operation sign after the a number is a minus sign
(x -3)^2
Don't forget the rest of the equation from before
(x -3)^2 + (8 - 9)
(x -3)^2 - 1
So the equation is f(x) = (x -3)^2 - 1
