Answer:
6x^2√(-2x)
Step-by-step explanation:
√(-72x^5)
= √(-2x)(36x^4)
= 6x^2√(-2x)
I’m pretty sure u just have to subtract 225-80
Answer:
The scale factor is 5 because the increase in each side of the shape is *5
Answer:
p = aq + b/q^2
The constants of proportionality here are a and b
11 = 2a + b/4 ----- i x 5
25.16 = 5a + b/25 ------ ii x 2
Multiply equation i by 5 and equation ii by 2
55 = 10a + 5b/4 ----- iii
50.32 = 10a + 2b/25 ----- ivStep-by-step explanation:
Put the value of b in equation iv
50.32 = 10a + 8/25
Multiply through by 25
1258 = 250a + 8
a = 5
p =5q + 4/q^2
Therefore using this equation put into the equation the value of q which is 7
p = 5(7) + 4/(7)^2
p = 35 +4/49
p = 35.082
