Translations, reflections, and rotations always result in a figure that is congruent. Only dilations with a scale factor other than 1 will give a similar, but not congruent, figure.
The 1st and 4th selections apply.
Answer:
A=9in,b =9in
Step-by-step explanation:
This is a right angled triangle
Formula = a2×b2=c2 (ie sq of both adj sides equals the sq of the longest side)
So, a2 × b2 = c2
But both sides are equal, so we can as well say 2(a2) = (9|2)^2
2a^2 = 162
Divide through by 2
A^2 = 81
So, a = |81
A = 9
And since both sides are equal, a = b = 9
Answer:
0.37
Step-by-step explanation:
5x^2-6x-7=0
25x-6x-7=0
19x-7=0
19x=7
0.37
#1 - We're doing 3 * 3 * 3, so 3 * 3 is 9 and 9 * 3 is 27. So the answer you are looking for is C.) 27.
#2 - The answer is C.) 6/7. (Couldn't figure out a way to explain this sorry...)
