The answer is 28
30+12-18-7+11= 28
First off, you need to rewrite the equation as 3*2*3
Then you multiply 3 by 2 to get 6.
Then you multiply 6 by 3 to get 18.
Then the answer is 18.
Hope this helps :)
Answer:
As shown in picture, this is a trapezoid.
The area of a trapezoid is calculated by:
A = (base1 + base2) x height x (1/2)
To work out A, we need to find out base1, base2, and height.
base1 = YZ = ![\sqrt{(Zx - Yx)^{2} + (Zy - Yy)^{2} } = \sqrt{(5 - 2)^{2} + (5 - 5)^{2} } = 3](https://tex.z-dn.net/?f=%5Csqrt%7B%28Zx%20-%20Yx%29%5E%7B2%7D%20%2B%20%28Zy%20-%20Yy%29%5E%7B2%7D%20%7D%20%3D%20%5Csqrt%7B%285%20-%202%29%5E%7B2%7D%20%2B%20%285%20-%205%29%5E%7B2%7D%20%7D%20%3D%203)
base2 = XW =![\sqrt{(Wx - Xx)^{2} + (Wy - Xy)^{2} } = \sqrt{(8 - 1)^{2} + (1 - 1)^{2} } = 7](https://tex.z-dn.net/?f=%5Csqrt%7B%28Wx%20-%20Xx%29%5E%7B2%7D%20%2B%20%28Wy%20-%20Xy%29%5E%7B2%7D%20%7D%20%3D%20%5Csqrt%7B%288%20-%201%29%5E%7B2%7D%20%2B%20%281%20-%201%29%5E%7B2%7D%20%7D%20%3D%207)
Otherwise, the height (distance between base1 and base2) is 4 as shown in picture.
=> A = (3 + 7) x 4 x (1/2) = 20
Hope this helps!

Answer:
B is the answer
Step-by-step explanation:
all the best
Answer:
Yes she has enough walnuts for her two recipes
Step-by-step explanation:
Total number of walnuts that Marni has = 11 ounces
She has two receipe
First recipe = 6 ounces
Second recipe = 1/4 pounds
Hence,
To find out if she has enough:.we add up the number of ounces from both recipes
The second recipe is in pounds hence, we convert to ounces.
1 pound = 16 ounces
1/4 pound =
Cross Multiply
= 1/4 pounds × 16 ounces/1 pound
= 4 ounces
Hence, we can add up now
First recipe + Second recipe
= 6 ounces + 4 ounces
= 10 ounces.
Since both recipes would require a total of 10 ounces of walnuts and Marin has 11 ounces, we can conclude that Marin has enough ounces of walnuts for her two recipes.
