The square is 130 in squared and the other shape is 54 in squared. If you're looking for the sum of the whole thing, its 185 in squared.
square: 13*10=130
triangle: 7*4= 28/2=14
rectangle: 10*4=40
Hello there,
1st attachment:
So in order to find this answer. We need to know that in a CUBE there is L*W*H. Your answer would be A.) 1125 because when we do 1125 3 times (L*W*H). . . It give's us 3375.
2nd attachment:
Your answer would be D.) 5,832m³.
My reason I say this is because when you do 18 square root to 3. It will give you 5,832m³
3rd attachment:
Your correct answer would be 80mm³. So this is what I did. C wouldn't be the wrong answer because that answer is in "inches" and we want to find the answer in "mm³" So when we do 2*2*2. We get 8cm. We need to find the answer in "mm³" "8cm" converted in "mm³" would equal 80mm³.
Hope this helps.

Answer:
it it two
Step-by-step explanation:
Answer:
9ab - 9a +1
Step-by-step explanation:
first, we can distribute the negative sign to the second set of parentheses.
-(-4ab + 5) becomes + 4ab - 5
now let's put the values in (5ab-9a-4) side by side with the corresponding values in + 4ab - 5
5ab + 4ab - 9a - 4 - 5
= 9ab - 9a - 9, because 5ab + 4ab = 9ab, -9a is alone, and -4 - 5 = -9.
Answer:
proof below
Step-by-step explanation:
Remember that a number is even if it is expressed so n = 2k. It is odd if it is in the form 2k + 1 (k is just an integer)
Let's say we have to odd numbers, 2a + 1, and 2b + 1. We are after the sum of their squares, so we have (2a + 1)^2 + (2b + 1)^2. Now let's expand this;
(2a + 1)^2 + (2b + 1)^2 = 4a^2 + 4a + 4b + 4b^2 + 4b + 2
= 2(2a^2 + 2a + 2b^2 + 2b + 1)
Now the sum in the parenthesis, 2a^2 + 2a + 2b^2 + 2b + 1, is just another integer, which we can pose as k. Remember that 2 times any random integer, either odd or even, is always even. Therefore the sum of the squares of any two odd numbers is always even.
