Answer:
56
Step-by-step explanation:
2 times 4 = 8
area of a triangle = b/2
so
8 * 12 = 96
96/2 = 48
48 plus 8 = 56
Answer:
The negative property is a sign used when a number goes below zero
Step-by-step explanation:
if that is the negative you are talking about
2x + 1 = 9
First step is to remove the integer (whole number)
Remove 1
2x = 8
Then divide by 2 to find x
x = 4
P = 58 inches
58 = 2 x height + 2 x width
58 = 2h + 2w
58 = 2 x 18 + 2w
58 = 36 + 2w
Get rid of the whole numbers
22 = 2w
Divide b 2 to find w
w = 11
Answer:
Equation: 720=(8x-1)+110+(5x+36)+116+(7x+19)+(6x-2)
x=17
Step-by-step explanation:
A 6 sided polygon is 720° degrees
so
720=(8x-1)+110+(5x+36)+116+(7x+19)+(6x-2)
Simplify
720=(8x+5x+7x+6x)+(−1+110+36+116+19+−2)
Combine like terms:
720=26x+278
flip equation:
26x+278=720
subtract 278 from both sides
26x=442
divide by 26 both sides:
x=17

The correct order of reasons that complete the proof about the rectangle and square is that D. definition of congruence, distance formula if two consecutive sides of a rectangle are congruent, then it's a square.
<h3>What is congruence?</h3>
It should be noted that congruence simply means an agreement or a correspondence between shapes.
In geoemtry, it should be noted that figures are said to be congruent if it is possible to superpose one of them on another.
It should be noted that the opposite sides of a rectangle are parallel while in a square, all the sides that are given are equal.
Therefore, the correct order of reasons that complete the proof about the rectangle and square is the definition of congruence, and that if two consecutive sides of a rectangle are congruent, then it's a square.
In conclusion, the correct option is D.
