Answer:
x≥2 2/5 or x≥ 2.4 or [2.4,∞)
Step-by-step explanation:
2x+7≤3x-5
7+5≤3x+2x
12≤5x
x≥12/5 or x≥2 2/5 or x≥2.4
Answer:
<u>Congruent pairs of triangles:</u>
ΔABD ≅ ΔDCB
- AB≅CD - given
- ∠ABD ≅ ∠CDB - given
- BD≅DB - common side
- SAS - two sides and the included angle
ΔABD ≅ ΔEFD - SAS
- AB≅EF - given
- ∠ABD ≅ ∠EFD - given
- ∠ADB ≅ ∠EDF - vertical angles
- AAS - two angles and non-included side
<u>By using the above two we can state that:</u>
ΔBDC ≅ ΔDFE - by ASA or SSS
because
- BD ≅ DF (corresponding parts)
- AD ≅ BC (corresponding parts)
- AD ≅ ED (corresponding parts)
- and therefore BC ≅ ED
<u>We can't prove that:</u>
- ΔAGD is congruent with any of the others as not enough information
There is one side and one angle and we can' t get two angles or two sides with included angle. Maximum we can get is SSA which doesn't guarantee the congruence.
16y² - x² = 4²y² - x² = (4y)² - x² = (4y-x)(4y+x) ← dfference of squeares

25%
Step-by-step explanation:
Number of games The Pelicans won last year= 16
Number of games The Pelicans won this year= 20
PI= percentage of increase D= difference between reference year and current year
R= Reference year
![PI= D/R\\PI= (20-16)/16\\PI=4/16\\PI=1/4](https://tex.z-dn.net/?f=PI%3D%20D%2FR%5C%5CPI%3D%20%2820-16%29%2F16%5C%5CPI%3D4%2F16%5C%5CPI%3D1%2F4)
PI=1/4= 25%
