Answer:
i like science because its combines one of my favorite subjects and turns it into logic.
A. $45/100 = 0.45
0.45 x 130 = $58.50
Guitar S.P = $58.50
b. $104/130 = 0.80
0.80 x 100 = $80
Store paid: $80
Answer:
B
Step-by-step explanation:
Because to find out if two triangles are similar you need an ASA which can help determine if they are similar or not.
Answer:
so to factor out you find the greatest common factor of 14 and 7
if you have 2x-2 then you can factor out the 2 and get 2(x-1)
7=7*1
14=2*7
the greatest common factor is 7
14x-7=7(2x-1)
Answer:
4r^3+8r^2-5r-10
= 4r^2(r+2)-5(r+2) [Factorise out like terms; distributive law of multiplication to check]
=(4r^2-5)(r+2) [Combine expressions]
