The <em>correct answer</em> is:
False.
Explanation:
An undefined term <em>can</em> be used in a proof.
There are three fundamental undefined terms in geometry: point, line and plane. All three of these can be used in a proof; therefore the statement that an undefined term cannot be used in a proof is false.
Remember times is multiplication and sum is addition. The symbol for less than is <.
3 * (4+T) < 40
To solve, use distributive property and rearrange.
3*4 + 3T < 40
12 + 3T < 40
3T < 28
T < 28/3*

Answer:
area of a triangle = 0.5 X base X height
0.5 X 4 X 4 = 8 cm^
area of a rectangle l X w
3 X 5 = 15 cm^
area of a parallelogram = base X height
5 X 3 = 15 cm^
add totals together
15 + 15 + 8 = 38 cm^
Answer: 19 pieces at original price and 71 pieces sold at reduced price.
Let x=number sold for original price, $9.50 and y = number sold at reduced price $7.50.
So we have 2 equations.
x+y=90 => x=90-y (eqn 1)
9.5x + 7.5y = 713. (eqn 2)
sub (eqn 1) => (eqn 2)
9.5(90-y) + 7.5y = 713
855-9.5y+7.5y = 713
855-713 = 2y
142 = 2y
y = 142/2
y = 71 (eqn 3)
sub (eqn 3) => (eqn 1)
x = 90 - 71
x = 19
These are the formulas right?.. I hope so, anyways..
- f(n)= 2^(n-1) -1
- g(n)=3n+6
f(7)=2^{7-1}-1 - f(7)=2^{6}-1 - f(7)=64-1 - f<u>(7) = 63
</u>
g(10)=3\X 10+6 - g(10)=30+6 - g<u>(10) = 36</u>
= <u>f(7)>g(10)</u>
I hope that it helped..
