V = (4,-3,5)
w = (2,6,-1)
z = (3,0,4)
u = 0.5 v - w + 2 z = 0.5 (4,-3,5) - (2,6,-1) + 2 (3,0,4)
= ( [0.5 * 4 - 2 + 2 *3] , [0.5*-3-6+2*0] , [0.5*5--1+2*4] )
= ( 6 , -7.5 , 11.5 )
The correct answer is option D
Answer/Step-by-step explanation:
1. Only one side and an included angle is known. To prove that both triangles are congruent by the SAS Congruence Theorem, an additional information such as a corresponding second side (KJ, and HJ) must be given to be equal to each other.
KJ = HJ
2. Additional information such as a second corresponding angle (angles C and W must be known to prove both triangles are congruent by SAS.
<C = <W
3. Additional information needed is a second corresponding angles must be known to prove the AAS.
4. Additional information needed is the corresponding angles, R and L, which should be equal to prove the ASA.
<R = L
5. Additional information needed: <C = <H
Answer: 30cm
Step-by-step explanation:
The area of a rectangle is determined by length times width
Equation: A=LW
10cm×3cm = 30cm
