12.) A rectangular garden bas a perimeter of 50 feet. The width of the garden is 7 feet. What is the area of the garden? 50 feet xi feet A. 18 ft? B. . 126 ft C. 50 ft D 350 ft​

126

Step-by-step explanation:

Perimeter=2(l+w)

50/2=2525-w

25-7=18

Area= lxw

18x7=126

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
