Answer:
3rd answer : 3n - 8 = n + 2
Step-by-step explanation:
difference means minus or-
more than means plus
is means the equal sign
3n - 8 = 2 + n
We have the following givens:
a=25
b=16
c=9
We can make use of the Laws of Cosines in solving the angle A such as:
cos A = (b²+c²-a²)/2bc
cos A =((16)²+9²-(25)²)/1*16*9
A=180°
tan (A/2)=tan(180/2)
Answer:
#1 20
#2 17
#3 14
#4 14
#5 12
#6 14
#7 10
#8. 20
#9. 20
Step-by-step explanation:
1 12+8=20
2 10+7=17
3 8+6=14
4 8+6=14
5 10+2=12
6. 8+6=14
7 4+6=10
8. 12+8=20
9 14+6=20
Now honey I can't do all your work for you im.not trying to be mean but work some.out heres a tip use a calculator to help you when you get stuck ask me your question and then I will hold you ok
Answer:
Perimeter expression: 3x-3+3x+x+4
Area expression: ( (3x-3)*(x+4) ) / 2
X= 5
Step-by-step explanation:
Perimeter is all the sides added together.
Area is base times height divided by 2
If perimeter is equal to 36 set the perimeter equation to 36 and solve for x.
