A) Why are all parallelograms not rectangles?

1 answer:

8 0

a) Rectangles always have 4 right angles (90 degrees), but parallelograms do not always have 4 right angles rather they can, but do not have to. Rectangles have to.

b) A square is a type of rectangle, but a rectangle is not a type of square. Both rectangles & squares have 4 right angles and are always quadrilaterals, but squares always have all sides that have the same length, but rectangles do not have to have their sides all equivalent lengths.

c) In the case of a parallelogram, the opposite sides are equal whereas in a rhombus all four sides are equal.

1) 8

2) $-\frac{3}{4}=-\frac{6}{8}$ , so it is equal to $-\frac{6}{8}+\frac{5}{8}$

3) 1/8

-34 + 91 = -3 (4x + 1) + 6x

ra1l [238]

$-34 + 91 = -3(4x+1) + 6x\\57 = -12x - 3 + 6x\\6x = -60\\x= -10\\$

Thus x = -10.

Hope that helps!

Solve for each variable and tell how you found the value of each.

AleksAgata [21]

Answer:

A:38 c:54

Step-by-step explanation:

First off, I did the easiest which was a. i found the value of A by subtracting 180 by 142. because a flat line is 180 degrees.

For C, It was more difficult. I subtracted 88 by the value of A, since the value of A is the same as the one next to 88. So I subtracted 126 (88+38) and got 54.

Fortunately, I couldn't figure out B though, but i think it is a similar answer to c.
