Answer:
5x²
Step-by-step explanation:
the greatest number each term can be multiplied by
Answer:
4x4x4 = 64 cubic ft
1 cubic foot = 7.48 gallons
64 x 7.48 = 478.72 gallons
Answer B I’m not sure if it’s right
Answer:
Angle A= 77.14°
Angle B= 102.86°
Step-by-step explanation:
Supplementary angles are angles that add up to 180°, as stated in the question.
This means that Angle A + Angle B= 180°
The measure of Angle A to Angle B is 3:4
3:4 --------> 3+4 = 7 total parts
Hence, angle A will be 3/7 of the total angle (180°)
angle B will be 4/7 of the total angle (180°)
That is, angle A = 3/7 × 180° = 77.1428°
angle B= 4/7 × 180° = 102.857°
Approximately, angle A = 77.14° while angle B= 102.86°
