The voume is 18.6 square inchs
5√7 × 3√14 = 5 × 3√(7 × 14)
= 15√98
= 105√2
Answer:
44
Step-by-step explanation:
these triangles are similar, so the proportions of the sides will be the same. Since the small triangle's proportions are 4:4, the bigger one's will be 44:44
x= 3+√5/4,3-√5/4
Step-by-step explanation:
1.In general, given ax^2+bx+c=0, there exists two solutions where:
x= -b+√b^2 - 4ac/2a, -b-√b^2-4ac/2a
2.In this case, a=4, b=-6 and c=1.
x=6+√(-6)^2-4×4/2×4, 6-√(-6)^2-4×4/2×4
3.Simplify.
x=6+2√5/8, 6-√5/8
4.Simplify solutions.
x=3+√5/4, 3-√5/4
