<span>Write the expression..3 more than twice a number k? </span>2 × k +3
Your blank would be 5.
If you write it out, it is 5(8+3)=8x+3x
So if you distribute the left it is 8(5)+3(5)...
So like on the right one, you x=5

Perimeter = 65.9 units
Area = 96.6 sq. units
sin = opposite / hypotenuse
sin 62 = 27.6/m
m = 27.6/62
m = 31.3 (nearest tenth)
Perimeter:
7 + 31.3 + 27.6
= 65.9 units
Area:
7 x 27.6 x 1/2
= 96.6 sq. units
Answer:
x=-6
Step-by-step explanation:
2x+1=-x-5
3x+1=-5
3x=-6
x=-2
