Help please

Answer: No it's not possible to form a triangle

Why not? Because the shorter sides 2 ft and 3 ft don't add to a result longer than 7 ft

2+3 = 5

For a triangle to be possible, the sum of any two sides must be larger than the third side. Refer to the triangle inequality theorem.

Need help with a math problem please! Thank you
kenny6666 [7]

f(x).g(x) = (x^2+6x)(2x^3) = 2x^5+12x^4

f(0).g(2) =(0^2+6*0)(2*2^3) =0*16=0

f(1).g(1)=(1^2+6*1)(2*1^3)=(1+6)(2*1)=7*2=14

g(x).g(x)=(2x^3)(2x^3)=2*2*x^3*x^3=4x^6

Pls help me solve surds , √75 ,√48, √12,√125,√28. pls help​
Goshia [24]
√75 = √(5²×3) = √5² √3 = 5√3 = 8.66

√48 = √(4²×3) = √4² √3 = 4√3 = 6.93

√12 = √(2²×3) = √2² √3 = 2√3 = 3.46

√125 = √(5²×3) = √5² √3 = 5√3 = 11.18

√28 = √(2²×7) = √2² √7 = 2√7 = 5.29

DerKrebs [107]
Given that the original price of the model boat kit is $67.53 and he has a coupon of $25 off if a purchase is $50 or more. Since the purchase is more than $50, we will deduct 25 from 67.53 so the discounted price of the model boat kit would be $42.53. Hope this answers your question.
