Answer:
The surface area of the paperweight is 
Step-by-step explanation:
we know that
The surface area of the triangular prism is equal to the area of its triangular base plus the area of its three triangular lateral faces
so
<em>Find the area of its triangular base</em>
<em>Find the area of its three triangular lateral faces</em>
![SA=3[\frac{1}{2}(2)(2.2)]](https://tex.z-dn.net/?f=SA%3D3%5B%5Cfrac%7B1%7D%7B2%7D%282%29%282.2%29%5D)
Adds the areas
Answer:
x=-2 and y=2
Step-by-step explanation:
Do simultaneous equations
-8x + 4y = 24 <em>(multiply everything in the equation by -7)</em>
-7x + 7y = 28 <em>(multiply everything in the equation by 8)</em>
56x - 28y = -168
-56x + 56y = 224
<em>(add equations, ie add 'x' parts, 'y' parts, and numerical parts)</em>
<em> </em>28y = 56
∴y = 2
-8x + 4y = 24
-8x + 4(2) = 24
-8x = 16
∴x=-2
Lemme know if you have questions :D
The final expression is 
Step-by-step explanation:
The expression that we have is
In order to solve the expression, we start by applying the distributive property to the bracket. We get:
Simplifying,
Now we add the two terms in x, and we find:
Which is the final expression.
