3) 0.5(12m-22n)=0.5(12m)-0.5(22n)
=6m-11n
4) 2/3(18x+6z) =2/3(18x)-2/3(6z)
=12x-4z
5)2x+12=2(x+6)
6)12x+24=12(x+2)
Answer:
B, but I can't read C
Step-by-step explanation:
the sum of any 2 sides must be longer that the 3rd.
A is not correct, 2 + 15=17, needs to be greater.
B 1, 8, 8.1 so yes as 1+8 >8.1
C 2, 8.9, I cna't tell if that last number is 9 or 92?
Answer:
Step-by-step explanation:
We have that:
Now we can find a+b
Answer:
D. 10
Step-by-step explanation:
Since you divided by 2. You want to multiply to go back wards.
35×2=70
They already give you base(b=7) so to find the height you need to divide to go backwards since you multipled bh.
70÷7=10
now plug it in to see if the equation is right.
35= 1÷2 (7×10)
