Answer:
(0.5, 5.5)
Step-by-step explanation:
<span>Consider the triangles ERT and CTR.
|ER|=|CT| shown
(</span>Therefore, one can say that segment ER is congruent to segment CT.)
m(R)=m(T)= 90°shown
(By the definition of a rectangle, all four angles measure 90°)
|RT|=|TR|
so we have Side Angle Side congruence.
By the <span>(SAS) Theorem, the triangles are congruent.

Answer:
A=360in^2
Step-by-step explanation:
there are 5 faces, 2 triangular, 3 rectangular
Triangular:
A=(9 * 10)/2=45
Since there are 2 of them the total is 90 in^2 for the triangles
Rectangular:
A=10*9=90
Since there are 3 the total is 270in^2
Total surface area is A=270+90=360in^2
Answer:
x = -4
Step-by-step explanation:
Given: -2(4x + 4) - 3x - 2 = 34
To solve this equation, we have to isolate the variable. (Get x by itself).
We'll follow the PEMDAS rule as far as parentheses.
So, -2(4x + 4) - 3x - 2 = 34
= -8x - 8 - 3x - 2 = 34
Now, we have to get x by itself. To do this, we'll move the numbers without variables to the other side.
Hence:
-8x - 8 - 3x - 2 = 34
+8 +2 +8 +2
-8x - 3x = 34 + 8 + 2
Now, we'll simplify.
-11x = 44
Lastly, to rid the negative eleven from the x, we have to divide negative eleven by the rest of the equation.
-11x = 44
-------------
-11
x = -4
X/4 + 1 = -6
x/4 = -6 -1
x/4 = -7
x= -28
