Answer: x= 
Step-by-step explanation:
−(7−2x)+7=−7
To find the opposite of 7−2x, find the opposite of each term.
−7−(−2x)+7=−7
The opposite of −2x is 2x.
−7+2x+7=−7
Add −7 and 7 to get 0.
2x=−7
Divide both sides by 2.
Fraction −7/2 can be rewritten as −2/7 by extracting the negative sign.
No it won't. it's false
cuz proofs here.
(5²)+(12²)= (169)
√(169) = 13
.. so if 13 was the number at 14
it would have been true.
currently the answer is false
Answer:
15.98cm
Step-by-step explanation:
Given data
Volume= 602.88cm^3
Radius= 6cm
The formula for the volume of a cone is
V= 1/3 πr^2h
substitute
602.88= 1/3*3.142*6^2*h
602.88=1/3*3.142*36*h
602.88=37.704*h
h= 602.88/37.704
h= 15.98cm
Hence the height is 15.98cm
Answer:
C)
Step-by-step explanation:
First use distributive property: a(b +c) =a*b +a*c
-3x + 5(x +2) = -3x + 5*x +5*2
= -3x + 5x + 10 {Combine like terms}
= 2x + 10
(-3x) and 5x are like terms
