35 = 45 - n
think of it as money
45 dollars take away how many (n) = 35 dollars
45 - n =35
or you can subtract 45 from both sides
-n = 35-45
-n = -10
divide by -1 from both sides
n = 10

An equilateral triangle with side length 6 and an equilateral triangle with side length 15 determine whether the polygons are si

tino4ka555 [31]

An equilateral triangle with side length 6 is similar to an equilateral triangle with side length 15

Solution:

Given that we have to find whether the polygons are similar

An equilateral triangle with side length 6

An equilateral triangle is a triangle in which all three sides are equal

All three internal angles are also congruent to each other and are each 60°

Let ABC be a equilateral triangle with side length 6

Since all three sides are equal,

AB = 6

BC = 6

CA = 6

Also, angle A = 60 degrees and angle B = 60 degrees and angle C = 60 degrees

An equilateral triangle with side length 15

Let XYZ be a equilateral triangle with side length 15

Since all three sides are equal in equilateral triangle,

XY = 15

YZ = 15

ZX = 15

Also, angle X = 60 degrees and angle Y = 60 degrees and angle Z = 60 degrees

Two triangles are similar if they have the same angles and the side lengths are proportional.

Since,

$\frac{AB}{XY} = \frac{BC}{YZ} = \frac{CA}{ZX} = \frac{6}{15} = \frac{2}{5}$

Also,

Angle A = angle X = 60 degrees

Angle B = angle Y = 60 degrees

Angle C = angle Z = 60 degrees

Since equilateral triangles all have the same angles, and all side lengths are equal, any two equilateral triangles must be similar.

Archy [21]

Part 1) Smooth curve going up the Origin, means, the distance of the bus is increasing with increase in time. In other words, Bus is in the motion.

Part 2) Distance is constant here & Bus is not moving at all.

Part 3) Distance is decreasing, means bus in moving in opposite direction, and it is said to be the negative displacement.

Part 4) Again, The Distance is constant here & Bus is not moving at all.

Part 5) Here, Displacement is negative, which means bus is moving in the opposite direction and reached the starting point.

Part B) It is Increasing at: Part 1
It is decreasing at: Part 3 & 5
It is constant at: Part 2 & 4

C.) Graph is non-linear, as it shows deviation through the complete journey of the Bus.

Hope this helps!

netineya [11]

Answer:

C. 4 + x = 3x - 2, 3

Step-by-step explanation:

4 + x = 3x - 2

Step 1: Subtract 3x from both sides; 4 - 2x = -2

Step 2: Then subtract 4 from both sides, -2x = -6

Step 3: Last divide -2 on both sides; -2x/-2 = -6/2

Solution: x= 3
