Answer:
B it is very simple my friend
Step-by-step explanation:
3.75 × 3.75 = 14.0
First you can apply the a²-b² = (a+b)(a-b) theorem, you'll get:
(p²)² - 9² = (p²+9)(p²-9), but that's not all, you can apply it again on the last factor:
(p²+9)(p²-3²) = (p²+9)(p+3)(p-3)
The first factor cannot be simplified like that, so that's the furthest factorization. So answer (3) is the right one.
The height of flagpole is 12.5 feet.
Step-by-step explanation:
Given,
Height of woman = 5 foot
Shadow of woman = 6 feet
Ratio of height to shadow = 5:6
Shadow of flagpole = 15 foot
Height of flagpole = x
Ratio of height to shadow = x:15
Using proportion;
Ratio of height to shadow :: Ratio of height to shadow
Product of mean = Product of extreme
Dividing both sides by 6
The height of flagpole is 12.5 feet.

For no real solution, you must have b^2 - 4ac of the quadratic formula be less than 0.
a = 1; b = 2; c = C
b^2 - 4ac < 0
2^2 - 4(1)(C) < 0
4 - 4C < 0
-4C < -4
C > 1
The only choice greater than 1 is 3.
Answer: the 4th choice, 3
7−4x+3=x−16−3x
Simplify
7−4x+3=x−16−3x
7+−4x+3=x+−16+−3x
(−4x)+(7+3)=(x+−3x)+(−16)(Combine Like Terms)
−4x+10=−2x+−16
−4x+10=−2x−16
Add 2x to both sides.
−4x+10+2x=−2x−16+2x
−2x+10=−16
Subtract 10 from both sides.
−2x+10−10=−16−10
−2x=−26
Divide both sides by -2.
−2x/−2=−26/−2
x=13
