-10x8
you distribute-2 through the parentheses & 4 too. Then you collect the like terms and calculate the sum.
Step-by-step explanation:
I think the answer is x=70
consider first number is = x
formula,
(n / 2)(first number + last number) = sum,
7/2(x+x+6)= 945
2x+6= 945×2/7
2x+6 = 270
2x= 270-6
x=264/2= 132
Answer the smallest number is 132.
The union of the sets are the values that appear in both sets when plotted in a Venn diagram and if I'm not mistaking, I think the right answer is (B)
Ellie: 20*15=300
Heather: 18*18= 324
Heather's floor model is greater by 24 feet
