A pyramid has a square base of 64 square centimeters. The triangular faces have a base of 8 centimeters and a height of 14 centimeters. What is the total surface area of the square pyramid?
Answer:
A cube has a lateral area of 676 square feet. ... The square base of the pyramid has side lengths of 32 centimeters. ... A rectangular prism has dimensions x units, 2x units, and x + 8 units. ... The triangular bases of a triangular prism have three congruent sides, each measuring 10 ... The height of the prism is 15 centimeters.
Step-by-step explanation:
2.5(12.75x + 24.50) = 188.75
1. Simplify both sides of the
equation
(remove parentheses
and/or combine like terms).
2. Use inverse operations and
properties of equality to
"undo" what is happening to
the variable. (use the
reverse order of operations
because we are undoing)
3. Check your answer by
substituting your answer
into the original equation.
Answer:
Step-by-step explanation:
First, in order to get rid of the parenthesis, you need to multiply 2.5 with whatever is in the parenthesis.
Multiply 2.5 on each side of the equation like this:
(12.75 x 2.5) (24.50 x 2.5) =188.75
Once you're finished, you should get 61.25 and 31.875x =188.75
Now in order to find 'x' you will need to subtract 61.25 to each side of the equation like this:
61.25 - 61.25 = 0
188.75 - 61.25 = 127.5
So now your equation should look like this:
31.875x = 127.5
You have to divide 31.875 by each side now.
Once you divide them, your final answer should be 4.
so x = 4.
I really hope this helps! ^^

A sign in a bakery gives these options:
15 cupcakes for $26
24 cupcakes for $42
40 cupcakes for $66
Find each unit price to the nearest cent, and show your reasoning.
Which option gives the lowest unit price?
Answer:
The lowest unit price would be last option
Step-by-step explanation:
We must divide the price by the amount of cupcakes we will be getting. Once we do that we'll get:
A. 1.77 cents
B. 1.75 cents
C. 1.65 cents
Hope this helped
Answer:
40 cupcakes for $66
Step-by-step explanation:
To find the unit price of something, dived the total amount by how may there are.
$26 divided by 15 cupcakes would be $1.7333333333, but if you round it up, it would be $1.74
$42 divided by 24 cupcakes would be $1.75
$66 divided by 40 cupcakes would be $1.65

look at all of this math. do it all or something for 50 points each ig
(a + b)2 = a2 + 2ab + b2
(a – b)2 = a2 – 2ab + b2
(a + b) (a – b) = a2 – b2
(x + a)(x + b) = x2 + (a + b)x + ab
(x + a)(x – b) = x2 + (a – b)x – ab
(x – a)(x + b) = x2 + (b – a)x – ab
(x – a)(x – b) = x2 – (a + b)x + ab
(a + b)3 = a3 + b3 + 3ab(a + b)
(a – b)3 = a3 – b3 – 3ab(a – b)
(x + y + z) 2 = x2 + y2 + z2 + 2xy + 2yz + 2xz
(x + y – z) 2 = x2 + y2 + z2 + 2xy – 2yz – 2xz
(x – y + z)2 = x2 + y2 + z2 – 2xy – 2yz + 2xz
(x – y – z)2 = x2 + y2 + z2 – 2xy + 2yz – 2xz
x3 + y3 + z3 – 3xyz = (x + y + z)(x2 + y2 + z2 – xy – yz -xz)
x2 + y2 = 1212 [(x + y)2 + (x – y)2]
(x + a) (x + b) (x + c) = x3 + (a + b +c)x2 + (ab + bc + ca)x + abc
x3 + y3 = (x + y) (x2 – xy + y2)
x3 – y3 = (x – y) (x2 + xy + y2)
x2 + y2 + z2 -xy – yz – zx = 1212 [(x-y)2 + (y-z)2 + (z-x)2]
