Answer:
I'll solve 27. To give you a hint.
m2 = 1 + 3x
180 = 1 + 3x
-1 -1
179 = 3x
/3 /3
x = 59.6666667 rounded up
x = 59.67
Answer:
22.5
Step-by-step explanation:
25-2.50=22.4
Answer:
= x^2 + 17/2x + 7
Step-by-step explanation:
x2+(x+7)(x+1)
Distribute:
=x2+(x)(x)+(x)(1)+(7)(x)+(7)(1)
=12x+x2+x+7x+7
Combine Like Terms:
=12x+x2+x+7x+7
=(x2)+(12x+x+7x)+(7)
=x2+172x+7
This statement shows the Commutative Property of Multiplication. It basically says that now matter order in which you multiply, you still have the same answer because, for example, 4*5=5*4. You can multiply 4 by 5 but you could also multiply 5 by 4 because multiplication is commutative. :)
A = 1/2 (2+7)(1.5)
A = 4.5 (1.5)
A = 6.75 yd^2
