-3r+5r=2r
This is the right answer
The answer is 3X + 12 because in he distributive property you must multiply both the 3X and the 4 by 3
3x1=3 hence the 3X
and 3x4 = 12 <span />
Answer:
Below in bold.
Step-by-step explanation:
b.
If we drop a perpendicular line from B to AC and mark the point D on AC, we have 2 right triangles, with AD = DC = 16 cm.
So tan O = BD/16 = 15/8
BD = (16*15)/8
= 2*15
= 30.
So the area of triangle ABC = 16*30
= 480 cm^2.
Answer:
A. 103º
B. 96º
C. m<4 = m<10
D. m<1 = m<16
E. m<5 = m<13
F. m<14 + m<15 = 180º
(Not entirely sure for C-F... But I hope this helps!)
Answer:
The answer is 490
Step-by-step explanation:
It takes 10 hours at 49MPH so you have to multiply 49 miles × 10 hours which gives you 490 miles
