Step-by-step explanation:

what answer is needed ? the result of the calculation ?

I assume this is the case.

remember that regarding the sequence of operations brackets are first, then exponents, then "dot" operations (× and ÷), and only at the very least come the "dash" operations (+ and -).

and that a combination of - + or + - results in -.

14 + 16 ÷ 2³ - (12 + 3²) ÷ 7 + 2 × (-5) =

14 + 16 ÷ 2³ - (12 + 9) ÷ 7 - 2 × 5 =

14 + 16 ÷ 2³ - 21 ÷ 7 - 2 × 5 =

14 + 16 ÷ 8 - 21 ÷ 7 - 2 × 5 =

14 + 2 - 3 - 10 = 3

4 and 11=40 X

5 and 12=60 YES!

The new dimensions of the garden are 5 m by 12 m, increased by 2, and the new area is 60 meters^2.

Tomtit [17]

Answer: There are 135 squares that will be in the completed quilt and No, the product change of you does not change the grouping of factors.

Step-by-step explanation:

Since we have given that

Number of sections = 3

Number of rows in each sections = 3

Number of square pieces in each row = 15

So, the number of squares that will be in the completed quilt would be

$3\times 3\times 15\\\\=9\times 15\\\\=135$

Hence, there are 135 squares that will be in the completed quilt and No, the product change of you does not change the grouping of factors.
