I think 54 because it's not a squared number
Step-by-step explanation:
8x8=64
9x9=81
12x12=144
So for a you need to add up all the numbers and for b you need to multiply all the numbers
Can you help me I posted a new question that is worth 50 points
Answer:
15
Step-by-step explanation:
Let 'l' be the length of the other leg
Using pythagoras theorem,
25² = 20² + l²
625 = 400 + l²
225 = l²
l = 15
1/5n - 12 = -7
or you can say
n/5 - 12 = -7
then if you solve...
n/5 - 12 = -7
+12 +12
n/5 = 5
times 5 on each side
n = 25
Perpendicular lines meet each other always at an angle of 90 while intersecting lines may or may not have an angle of 90.
Their opposite angles(made by intersecting lines) are always same.
And even, we can say every perpendicular lines as intersecting but can't say that every intersecting line is perpendicular.
