Hi there!

<u>Here is the step by step explanation into solving this :</u>

4 × (2² + 5)² ÷ 3 - 1

Start by solving the inside of the parentheses

2² = 2 × 2 = 4

4 + 5 = 9

Distribute the "²" to the whole parentheses

9² = 9 × 9 = 81


4 × 81 ÷ 3 - 1

Do the multiplication, then the division and lastly the subtraction

4 × 81 = 324

324 ÷ 3 = 108

108 - 1 = 107


The answer is : 107


There you go! I really hope this helped, if there's anything just let me know! :)

Answer:

The correct option is B

(-1)(1/2)(-1)(1)

Step-by-step explanation:

First thing to notice is that there is are two brackets with negative values, which means that the result must also be positive (or have two brackets with negative values).

Looking at the options, we can screen out options A and D, they have three brackets with negative values, and can't be chosen.

It is now between options B and C.

Option B, by inspection is simply 1/2

Option C is 12/4 = 3

The problem itself is 12/35

12/24 = 1/2

12/36 = 1/3

Since 12/35 is about 1/3, it is closer to 1/2 than 3, so 1/2 is the best option.

12. A flat, square roof needs a square patch in the corner to seal a leak. The side length of
NISA [10]

Answer:

Step-by-step explanation:

Area of the good part= area of whole roof - area of bad part

Since the roof is a square roof, the area will be calculated using the formulae for area of a square

Area of a square =length²

Area of good part =(x+12)²-x²

A= {(x+12)(x+12)} - x²

A = (x²+12x+12x+144) -x²

Open the bracket and rearrange the equation

A= x²-x²+24x+144

A=(24x+144) ft
