guapka [62]
To get the answer, first, you must find the amount in each box, so you must divide, 122 divided by 8, you should get 15.25, but that's not your answer. The question asks how many COMPLETE boxes, so just choose the whole number, which is 15. 15 is the answer.

Math sequences number patterns
grandymaker [24]

Answer:

see explanation

Step-by-step explanation:

(a)

Note the squared value in column 3 which is the square of 1 more than the row number, that is

row 2 → (2 + 1)² →3²

row 3 → (3 + 1)² → 4²

Find the square root of 676 = 26 → (25 + 1)² = 26²

Hence the row number is 25

(b)

The pattern in column 1 is [ row number × (row number + 2 ) + 1 ]

row number is n then n(n + 2) + 1 = n² + 2n + 1

Given 6(x) = (x+41, what is b(-10)?
prisoha [69]

The value of b(-10) is 31

Explanation:

The given expression is b(x)=x+41

We need to determine the value of b(-10)

The value of b(-10) can be determined by substituting x=-10 in the expression b(x)=x+41

Thus, we have,

b(-10)=-10+41

Adding the terms, we have,

b(-10)=31

Thus, the value is 31.

Therefore, the simplified value of the expression by substituting x=-10 in the expression b(x)=x+41 is 31.

Subtract 3/y-2 - 1/y+3
Helen [10]
To subtract fractions, we need a common denominator.

\frac{3}{y-2} - \frac{1}{y+3}

the common denominator will be (y-2)(y+3)

\frac{3(y+3)-1(y-2)}{(y-2)(y+3)}
\frac{3y + 9 - y + 2}{(y-2)(y+3)}
\frac{2y + 11}{(y-2)(y+3)}

The answer above will be the simplified form.
