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

Its 75 honestly how i did it was just 25x10 then 3x25 which is 75
Answer:
x = -2
Step-by-step explanation:
Answer:
76$
Step-by-step explanation:
114=.6y; y= original price
y=190, original price
190-114=76
A. -7/2
(1/4)^x+1=31
x+1=(-1/2)logbase2(31)-1
x=(-1/2)logbase2(31)-1
x=-3.5 or -7/2
