Can you explain more please
.7
7%
1/7
√ 7 In order technically .7 and 7% are the same if u simplify it or put in a calculator tbh
Answer:
x=7
Step-by-step explanation:
10+4x=5(x-6)+33
10+4x=5x-30+33
10+4x=5x+3
10=5x-4x+3
10=x+3
x=10-3
x=7
The square root of 48 n^9 can be determined by determining first the square root of the coefficient separately, then the variable, If the number is not a perfect square, then we get the nearest square. square root of 48 is 4 square root of 3. square root of 9 is equal to 3. Hence, the answer is 4n3 square root of 3.

Answer:
30
Step-by-step explanation:
The sequence of square counts is ...
170, 156, 142, 128
The differences from one row to the next are ...
-14, -14, -14
We see that the differences are constant, so we know the sequence is an arithmetic sequence with first term 170 and common difference -14. This means the n-th term is ...
an = a1 +d(n -1) . . . . . . for first term a1 and common difference d
an = 170 -14(n -1)
For n=11, the number of squares is ...
a11 = 170 -14(11 -1) = 30
There will be 30 squares in the 11th row.
