Answer:
C. square
Step-by-step explanation:
<u>Congruent</u> means "the same" (having the same shape and size).
Any four-sided, 2-dimensional shape with straight sides is called a <u>quadrilateral</u>.
There are 6 special types of quadrilaterals:
<u>Rectangle</u>
- Opposite sides are parallel and equal in length
- All interior angles are 90°
<u>Square</u>
- All sides are equal in length
- All interior angles are 90°
<u>Rhombus</u>
- All sides are equal in length
- Opposite sides are parallel
- Opposite angles are equal
<u>Parallelogram</u>
- Opposite sides parallel and equal in length
- Opposite angles are equal
<u>Trapezoid</u>
- One pair of opposite parallel sides
<u>Isosceles Trapezoid</u>
- One pair of opposite parallel sides
- One pair of non-parallel sides equal in length
- Two pairs of equal base angles
<u>Kite</u>
- Two pairs of adjacent sides equal in length
- The angles included between the sides of differing lengths are equal
<u>Conclusion</u>
A four-sided shape that has four congruent angles and sides is a SQUARE.
Answer:
9
Step-by-step explanation:
PEMDAS IS
parentheses
Exponents
Multiply and divide
Addition and subtraction
First you start with the parentheses so
1 + 2 = 3
Now you have 6/2 x 3
Multiply and divide means you either divide or multiply what ever comes first going left to right
So
6/2 = 3
3 x 3 = 9
If it was reversed we’d have
2 x 3/6 which would be
6/6 = 1
Answer:
-49,152
Step-by-step explanation:
Multiply everything by 4 until yo get to the 8 term.
4 is -192
5 is -768
6 is -3,072
7 is -12,228
8 is -49,152
Answer:
(1, 2)
Step-by-step explanation:
Given the equation of the lines x + 2y = 5 and 2x - 3y = -4
First we need to make x the subject of the formulas
For x+2y = 5
x = 5 - 2y ... 1
For 2x - 3y = -4
2x = -4+3y
x = (-4+3y)/2 ... 2
Equate 1 and 2
5 - 2y = (-4+3y)/2
2(5-2y) = -4+3y
10 - 4y = -4+3y
-4 -3y = -4-10
-7y = -14
y = 14/7
y = 2
Substitute y = 2 into 1
x = 5 = 2y
x = 5 - 2(2)
x = 5 - 4
x = 1
Hence the point where the lines meet will be at (1, 2)
