Answer:
80a^9 + 70a^8
Step-by-step explanation:
Use the distributive property and multiply each term in the expression by 10a7
10a7(8a2 + 7a)
80a9+70a8
Answer:
1:4
Step-by-step explanation:
1.2 cm of white fabric per 48 mm of colored fabric:
1.2 cm : 48 mm= 12 mm: 48 mm= 1:4
The ratio is: 1:4
First one is 7x^5 and the second is 10x^4 I believe
Step-by-step explanation:
a. the angle B in triangle ABC:
180-47=133°
angle C in ABC:
180-(40+133)=7°
using sine rule:
a/sin A= b/sin B= c/sin C
50/sin 7= BC/sin 40
BC= (50*sin40)/ sin7
=263.7 m
b.sin 47= opposite/hypotenuse
sin 47= CD/263.7
CD= sin 47*263.7
= 192.9
