N•2>8
then dive both sides 2n>8
and get n>4
25x25+20x25+20x15+15x25=1800 the answer is D.
Answer:
Step-by-step explanation: I think you skip count by 50s or something like that. So, it has to be 64.
Answer:
BD = 16
Step-by-step explanation:
By applying mean proportional theorem in the given right triangles,

AD × CD = BD²
8 × 32 = BD²
BD = √256
BD = 16
Therefore, measure of side BD = 16 units.
Multiply equation B by 2.
Multiply equation A by 2
Multiply equation B by 3.
Multiply equation A by -3
Answer: D
