step-by-step explanation:
i took the test: )
a28=58
a1=a1+(n-1)d
a28= 4+ (28-1)2
a28=4+(27)(2)
a28=4+54
x = 2
if sr parallel to ba then the sides bc and ac are in proportion, that is
= ← substitute values
= ( cross- multiply )
27x = 6(4x + 1)
27x = 24x + 6 ( subtract 24x from both sides )
3x = 6 ( divide both sides by 3 )
