1 → B
multiply each term in the parenthesis by the 6 outside
6(b-7) = 6b - 42
2 → D
multiply each term in the parenthesis by the 3 outside
3(4x+6y+2) = 12x+18y+6
3 → A
the value outside the parenthesis is -1, hence each term inside is multiplied by -1
-1(6x+5y) = -6x -5y
Answer:
width = 8 inches
length = 10 inches
Step-by-step explanation:
width= 12/1.5
= 8
length = 15/1.5
= 10
You have to square root 25/289 to solve X. The answer will be 5/17
2x + x = 180
This is because 2x is on one side while x is on the other, if those two angles add up they must add up to 180 because the two angles form a 180 degree angle or just a straight line
2x + x = 180
3x = 180
x = 60
A triangle that has 2 sides congruent is called an isosceles triangle.
A triangle that has all 3 sides congruent is called an equilateral triangle.
