Yoink:
hey imma yoink your points and not answer the question ok?
Jk:
jk, number 1 is b
number 2 is a
number 3 is d
and number 4 is c
The equation for area of a triangle is A= 1/2bh so a=1/2(12cm)(9.6cm)
520*.04=20.8, or closer to 21 spam emails.
B) c - 1/5c - 40 = 120
c- (original cost) - 1/5c (sale) - 40(coupon)= 120(final cost)
Hope that helps! :)
