Answer:
195.6
Step-by-step explanation:
area of base= 1/2 * 8 * 6.9 = 27.6
area of lateral face= 1/2 * 8 * 14 = 56
total surface area = 27.6 + 56 + 56 + 56 = 195.6
Answer:
b
Step-by-step explanation:
Answer:
Part A:
To find the area of a rectangle you want to take length times width
(2x+11)(6x+4) You want to solve by using the FOIL method
First, Outer, Inner, Last
First terms 2x*6x=12x^2, when you multiply numbers with exponents you want to add, which is how we got it to squared
Outer terms~ 2x*4=8x, we take out two outer terms and times them by each other
Inner terms~ 11*6x=66x, we take our inner two terms and times them to each other
Last terms~ 11*4=44, we take the last two terms times each other
That now leaves us with
12x^2+8x+66x+44 Now we want to combine like terms to get:
12x^2+74x+44
Part B:
The degree is your highest exponent which in our case is 2
You would classify by how many different numbers you have:
This would be a trinomial because you have three different numbers: (12x^2, 74x, and 44)
Highest degree= 2
Classification= Trinomial
Part C:
Part A demonstrates the closure property because it shows that the polynomials are closed under the operations of adding, subtraction, and multiplying
Hope this helps ;)
12) The mistake that Liz made was instead of shading in 5% of the diagram, she shaded in 5 blocks, which is incorrect.
13) You would have to shade in only one block, because 5% of 20 (blocks) is 1.
Hey there!
I want you to think of radicals as like terms. In order to be able to combine like terms, you need the same <em>base </em>and <em>exponent. </em>
<em>For example, </em>
3x^2-y^2 <== same exponent but not same variable
3x^2-x^2 <=== could be combined because exponent (^2) and variable (x) are the same
So, for this question, you're looking for a radical that has 5 under the radical sign and 3 above the radical sign.
"B" is the right answer, because is ∛ and in the radical it has a √5.
I hope this helps!
