Answer:
x = 3; y = 11
Step-by-step explanation:
A parallelogram has two pairs of congruent opposite sides. For quadrilateral ABCD to be a parallelogram, sides AB and CD must be congruent, and sides AD and BC must be congruent.
AB = CD
2y + 2 = 3y - 9
-y = -11
y = 11
AD = BC
3x + 6 = y + 4
We already know y = 11, so we substitute 11 for y.
3x + 6 = 11 + 4
3x + 6 = 15
3x = 9
x = 3
Answer: x = 3; y = 11
Answer:
54m^2
Step-by-step explanation:
Each square has a equal sides, which is 3m
in order to find the surface area, it's
Formula : Base x height = Area
The total surface area would be all the area's added together
3x3=9cm^2
so each square is 9m^2
there are 6 squares so
9+9+9+9+9+9=54m^2
or you can do 9x6=54m^2
Answer:
10 boys
Step-by-step explanation:
6:2 simplfies to 3:1 30 / 3 = 10
30:10 simplfies down to 6:2
Answer:
Area = 12
i attached the formula to ger the area with the perimeter
Step-by-step explanation:
Standard form is ax^2 + bx + c. Vertex form is a(x-h)^2 + k, which reveals the vertex and axis of symmetry. Factored form is a(x-r)(x-s), which reveals the roots.
