28.) 8x + 28 - 16y
Find the GCF (greater common factor) or the smallest number that divide
8, 28 and 16 ALLTOGETHER.
8 = 2 x 4
28 = 7 x 4
16 = 4 x 4, so 4 is the GCF: Now you take 4 as a common factor
4(2x + 7 + 4y)

Answer:
1.
2.(a)Therefore , Side LJ =side CA
(b) BC = KL
Step-by-step explanation:
1.
we know that, vertically opposite angles are congruent .




2.
(a)SAS = side,angle , side
Given ,side AB = side KJ
and ∠CAB= ∠LJK
All Pythagorean Triples are unique.
Since side AB = side KJ
Therefore , Side LJ =side CA
It satisfies SAS postulate ThereforeΔABC≅ΔKJL
(b)
HL Theorem: If hypotenuse and one leg of of a right triangle are congruent to the hypotenuse and one leg of of other right triangle , then the triangle congruent.
Since,
All Pythagorean Triples are unique.
Then hypotenuse of ΔABC=ΔLKJ ⇔BC = KL
