Step-by-step explanation:
Answer:
Step-by-step explanation:
A. 3x+21=6x-60 -> 3x=81 -> x=27. So false. The value of x=27.
B. True. Alternate interior angles theorem.
C. False. The marked angles are alternate interior angles.
Answer:
a = 7.21
Step-by-step explanation:
Remark
This just uses a^2 + b^2 = c^2. You know 2 of the three things there.
<em><u>Givens</u></em>
Solution
a^2 + b^2 = c^2 Substitute the givens
a^2 + 12^2 = 14^2 Expand
a^2 + 144 = 196 Subtract 144 from both sides
a^2 = 196 - 144 Collect like terms on the right
a^2 = 52 Take the square root of both sides.
sqrt(a^2) = sqrt(52)
a = 7.2111
a = 7.21 Answer
4 consecutive odd integers....x , x + 2, x + 4, x + 6
product of 2 smaller numbers is 64 less then the product of the 2 larger numbers....
x(x + 2) = (x + 4)(x + 6) - 64
x^2 + 2x = (x^2 + 10x + 24 - 64)
x^2 + 2x = x^2 + 10x - 40
2x = 10x - 40
2x - 10x = -40
-8x = -40
x = -40/-8
x = 5
x + 2 = 5 + 2 = 7
x + 4 = 5 + 4 = 9
x + 6 = 5 + 6 = 11
ur numbers are : 5,7,9,and 11
