Answer:
Step-by-step explanation:
4x + 3y + x + 4y
= 4x + x + 3y + 4y
= 5x + 7y
4x + 3y + 2x - y
= 4x + 2x + 3y - y
= 6x + 2y
4x + 5y - ( x + 4y )
= 4x + 5y - x - 4y
= 4x - x + 5y - 4y
= 3x + y
2x - y + 3x + y
= 2x + 3x - y + y
= 5x + 0
= 5x
For the 1st one RSV = TSU (Vertical angles are congruent)
9x - 28 = 6x + 2
3x = 30
x = 10
RSV = 62
The 2nd one
Alternate exterior angles are congruent
Thus
10x + 5 = 125
10x = 120
x = 12
The 3rd one
When triangles are similar their sides are promotional and their angles are congruent
thus
A and D
The 4th one
Find Angle A
Angle A + 3Angle A + 76 = 180
4 Angle A = 104
Angle A = 26
Answer:
Step-by-step explanation:
-9= x -3 (add 3 to both sides of the equal sign)
-9+3 = x -3+3
-6 = x
solved :)
Answer:
Oh yeah u clucking bluckersssssssssssssssss
Step-by-step explanation:
(-7) squared is 49.
(-7) squared = -7 x -7 = 49
Basically, anything is squared with a number, just double it the number.
