Perimeter of the triangle, a+b+c
In this case, a=b=c=28
So, perimeter would be 28*3 = 84 cm
Hello friend!
1/3(9x+12)=15
We move all terms to the left:
1/3(9x+12)-(15)=0
Domain of the equation: 3(9x+12)!=0
x∈R
We multiply all the terms by the denominator
-15*3(9x+12)+1=0
multiply elements
-45x(9+1=0
Answer:
For problem 31: 25 counters in the 5th figure, 81 counters in the 9th figure, and 121 counters in the 11th figure.
Step-by-step explanation:
Since in the examples it shows 1 exponent 2, 2 exponent 2, and 3 exponent 2, that means all the rest will have 2 as an exponent. So the fifth figure would be 5 exponent 2, which is 5 times 5 = 25. The 9th figure would be 9 exponent 2, which is 9 times 9 = 81. The 11th figure would be 11 exponent 2, which is 11 times 11 = 121.
Is that all, or do you need answers for #'s 32, 33, and 34?
D because there sides are congruent
We must know how many inches the plant grows in one month.
13 ÷ 5 = 2.6
The plant grows 2.6 inches a month.
Simply multiply 2.6 by the corresponding months to fill in the rest of the boxes.
