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

faust18 [17]

Given equation is : $x^{2}-4=0$

Solving it we get,

$x^{2}=4$

$\sqrt{x}=\sqrt{4}$ and $\sqrt{x}=-\sqrt{4}$

This gives $x=2$ and $x=-2$ or we can say the roots are $(x+2)(x-2)$

Here Stefan is right, the root has a multiplicity of 1.

Mrs. Jackson gave sum of money to her son and daughter in the ratio 8:9 her daughter received $3,060. How much did Mrs.Jackson g

noname [10]

Answer: $5780

Step-by-step explanation:

Mrs. Jackson gave sum of money to her son and daughter in the ratio 8:9 and her daughter received $3,060. To get the total amount given to the children goes thus:

Son = 8

Daughter= 9

Total = 8+9 = 17

Let the total amount given to the children be y. Since the daughter's share is $3060.

= 9/17 × y = 3060

= 9y/17 = 3060

9y = 3060 × 17

9y = 52020

y = 52020/9

y = 5780

Mrs Jackson gave out $5780

Steph needs to help her parents put a fence around their pool. They want the fence to be square and want each side to measure 6

marin [14]

Answer:

14 meters

Step-by-step explanation:

Each side of the square fence = 6 meters

Perimeter of the square fence = 4 × length

= 4 × 6

= 24 meters

They already have 10 meters of fencing

How many more meters of fencing should they buy?

= Total meters - available meters

= 24 meters - 10 meters

= 14 meters
