Answer:
C
Step-by-step explanation:
180-33-88 equals 59 and in order for the two triangles to be congruent it would need to be 58, which is present as an angle in the other triangle
Answer:spread out from and larger
Step-by-step explanation:
Xy = 940
<span>and </span>
<span>Cost = 5(2x) + 5y + 10y (I chose y to be the side with brick). The cost equation simplifies to: </span>
<span>C = 10x + 15y </span>
<span>Replace y in the cost equation with 940/x: </span>
<span>C = 10x + 15(940/x) </span>
<span>C = 10x + 14100/x <---this is the equation you need to minimize. </span>
<span>C' = 10 - 14100/x^2 </span>
<span>10 - 14100/x^2 = 0 </span>
<span>14100/x^2 = 10 </span>
<span>x^2 = 14100/10 = 1410 </span>
<span>x = sqrt(1410) = 37.55 </span>
<span>y = 25.03 <---this is the length of the brick fence.</span>
3xy+9=33
A. 3*8*1+9=33; 3*2*6+9=45
(A. is not your answer)
B. 3*1*11+9=42; 3*2*6+9=45
(B. is not your answer)
C. 3*1*8+9=33; 3*8*1+9=33
(c. is your answer)
D. 3*1*8+9=33; 3*1*11+9=42
Your final answer, If that is confusing, is C. (1,8) and (8,1)
