Congruent because you can map the triangles using a reflection across the y-axis which is a rigid motion
I think it’s 5. Since logarithms are used to find the original value of a power. Therefore you reverse it and do square root of 25 which is +5 or -5
Answer:
x=1/2; y=-6
Step-by-step explanation:
2x-2=-2x-5
4x=2
x=1/2
y=-1-5
y=-6
We have
AP = 34,36,38......,234
a, (first term) = 34
n ( total terms ) =?
d ( common difference ) = 2
so, a +(n-1)d =an
34+(n-1)*2 = 234
(n-1)2 = 234-34
n-1 = 200/2
n = 100+1
n =101
Now sum of the even no.
Sn = n/2( 2a+9n-1)d)
= 101/2 (2*34 +100*2)
= 101/2 * 268
=101 *134
= 13534
