Answer:
Step-by-step explanation:
11/12 × 4 = 11/3 = 3⅔
No because x=4 and y=-5 and when you plug it in you get 5(4)+2(-5)=8 20+-10=8 and 10= does not work so it is not a possible solution.
A^2 + 31 = 155 - I squared each of b and c for those numbers
a^2 = 155 - 31
a^2 = 124
a = 4 * sqrt(31)
Answer:
400 cm²
Step-by-step explanation:
25÷20 = 1.25
Area = 1.25 × 320
