Y=3x2 3x(0.5)=1.5+2=3.5 Y=3.5
3(0.5)X2 1.5X2=3 Y=3
1.5/2=0.75 Y=0.75
1.5-2=-0.5 Y= -0.5
hope that helps . let me know plz
Hence, The value of x in the congruent triangles abc and dec is 1
<h2>What is geometry?</h2>
the branch of mathematics concerned with the properties and relations of points, lines, surfaces, solids, and higher dimensional analogs.
<h3>How to solve?</h3>
The question implies that the triangles abc and dec are congruent triangles.
The congruent sides are,
ab = de
bc = ce = 4
ac = cd = 5
The congruent side ab = de implies that,
4x - 1 = x + 2
Collect like terms,
4x - x = 2 + 1
Evaluate the like terms,
3x = 3
Divide through by 3
x = 1
Hence, the value of x is 1

Answer:
a) a trapezoid
b) faces are "sides" so the answer is 6
First you simply have to substitute 2 in replace of all the a's, and -2 in replace of all of the b's
4((2)2+2(-2))
Then you want to follow the order of operations, PEMDAS (Parantheses-Exponent-Multiplication-Division-Addition-Subtraction), and multiply within the parantheses.
4(4+(-4))
Next you will add within the parantheses (So add the 4 and -4 together)
4(0)
Lastly multiply
0
Your answer is 0
