By applying algebra, radical and power properties, we find that the simplified form of (√2 + √3) · (√5 - √7) is equal to √10 + √15 - √14 - √21. (Correct choice: B)

<h3>How to simplify a product of two binomials with radical numbers</h3>

Herein we need to apply algebra and radical and power properties to simplify the expression described in the statement, whose procedure is shown below:

(√2 + √3) · (√5 - √7) Given
(√2 + √3) · √5 + (√2 + √3) · (- √7) Distributive property
√2 · √5 + √3 · √5 + √2 · (- √7) + √3 · (- √7) Distributive property
√10 + √15 - √14 - √21 (- a) · b = - a · b/ √a · √b = √a · b/Result

Answer:

2,850

Step-by-step explanation:

4.25 x 9 = 38.25

4.25 x 13 = 55.25

4.25 x 12 = 51

13.70 x 92 = 1260.4

3.28 x 130 = 426.4

8.06 x 126 = 1015.56

all totals would equal 2,846.86, which to the nearest would be $2,850

a farmer is buying fencing to surround a square field of area 3600m^2. What length of fencing does he need to buy?

kirill115 [55]

Answer:

240 m

Step-by-step explanation:

The area of a square field is 3600 m².

We need to find the length of fencing he needs to buy. It means we need to find the perimeter of the field.

The area of a square field is given by :

A = side²

So,

$s=\sqrt{3600} \ m\\\\s=60\ m$

Length of fencing = perimeter

= 4(s)

= 4(60)

= 240 m

So, he would need to buy 240 m of fencing.

Solve -3x2 + 30x - 90 = 0.

$-3x^{2}+30x-90=0 \\ \\ x^{2}-10x+30=0 \\ \\ \Delta=(-10)^{2}-4*1*30=100-20=-20 \\ \\ \sqrt{\Delta}= \sqrt{-20}=i \sqrt{20} =2i \sqrt{5} \\ \\ x_{1}= \frac{10-2i \sqrt{5} }{2} = 5-i \sqrt{5} \\ \\ x_{2}= \frac{10+2i \sqrt{5} }{2} = 5+i \sqrt{5}$

Joan wants to get a $1,000 loan from her bank. She finds out That the current interest rate is 17%. If Joan came to you for advi

Lady bird [3.3K]

I would tell her not to because not only does she have to pay back the 1000 but now she also has to pay back the interest on it. She should just wait or save up until she has 1000 that way she dont gotta pay extra.
