Answer:
8 sqrt(5)
Step-by-step explanation:
sqrt(45) + sqrt(125)
Rewriting
sqrt(9*5) + sqrt( 25 *5)
we know sqrt(ab) = sqrt(a) sqrt(b)
sqrt(9) sqrt(5) + sqrt(25) sqrt(5)
3 sqrt(5)+5 sqrt(5)
Add like terms
8 sqrt(5)
Answer:
the length is 40m
Step-by-step explanation:
Answer:
y >= 8
Step-by-step explanation:
This equation is written in vertex notation, so we know the vertex is (-5,8). The parabola opens upward because the coefficient of the squared term is positive. Therefore, the vertex is the minimum, meaning all y values will be greater than (or equal to) the y-coordinate of the vertex (which is 8). When we convert this into a mathematical inequality, we get y>=8.
Answer:
1/9
Step-by-step explanation:
27x+3 = 6
-3 -3
27x = 3
/27 /27
× = 3/27 = 1/9
Answer:
False
Step-by-step explanation:
3x4=12
12 divided by 3=4
4x8=32
32=34
Hence, this equation is false.
