Answer:
1st
Step-by-step explanation:
The two triangles are similar by AA
Firstly, we can see that angle LKM and QKR are congruent as they are vertical angles.
The second set can be identified by noticing that RM is a transversal through 2 parrallel lines LM and QR. That manes QRK, and LMK alternate interior angles, showing that the angles are congruent. Hence similarity by AA
Answer:
Step-by-step explanation:
we have
Solve for t
That means ----> isolate the variable t
Convert mixed number to an improper fraction first
substitute
Multiply by 4 both sides to remove the fraction
Distribute right side
Adds 128t both sides
Divide by 216 both sides
Simplify
Convert to mixed number
therefore
Answer:
u = x²
Step-by-step explanation:
4x⁴ − 21x² + 20 = 0
4(x²)² − 21x² + 20 = 0
If we substitute u = x²:
4u² − 21u + 20 = 0
Answer:
C) 4
Step-by-step explanation:
Just follow the same steps as the last one.
32x+2 = 33x-2
2+2=33x-32x
4=1x
X=4
