Answer:
do you have a pic
Step-by-step explanation:
Answer:
1a = 8 cu. in.
1b = 48 cu. yd.
1c = 15 cu. ft.
2a. 36 cu. yd.
2b = 126 cu. ft.
2c = 90 cu. ft.
3a = 112 cu. in.
3b = 60 cu. yd.
3c = 189 cu. ft.
Step-by-step explanation:
Answer:
60°
Step-by-step explanation:
Am equilateral triangle is a triangle that has all its sides and angles equal. Note that an equilateral triangle has 3 sides and angles.
Let the angles be a, b and c
The sum of angle in a triangle is 180°, hence;
a+b+c = 180°
Since a = b = c
The equation becomes;
a+a+a = 180°
3a = 180
a = 180/3
a = 60°
Hence the measure of the angles of an equilateral triangle is 60° for the three angles.
When simplifying you want to combine like terms so 14x²-12x² will equal 2x², now we move on to X, where 3x+11x will result in 14x, last we add up numbers without X so 4-3 is 1.
The Answer will end up being 2x²+14x+1 (B)
We need graphs to choose from sweetie
