116
Step-by-step explanation:
Pemdas so do the 10 × 12 first... you get 120 the you go left to right so 3 + 120 = 123... subtract 7 from that and you get 116.
Answer:
-0.6 cm/min
Step-by-step explanation:
The formula for the area of a triangle is ...
A = (1/2)bh
Solving for the base, we find ...
b = 2A/h
Then the rate of change of the base is ...
b' = 2(A'h -Ah')/h^2
Filling in the given values, we find the rate of change of the base to be ...
b' = 2((2 cm^2/min)(20 cm) -(160 cm^2)(1 cm/min))/(20 cm)^2
= 2(40-160)/400 cm/min
= -0.6 cm/min
The base is decreasing at 0.6 cm/minute.

Answer:
Step-by-step explanation:
Since you know both triangles are congruent, you can say that the corresponding sides are equal. For example, you can say:
17x+3 = 57
because they are corresponding sides of both triangles. To further solve the equation:
17x = 54 --> x = 54/17 --> <u>3 3/17</u>
Same thing for Y. lines PX and FD are congruent, so, you can say:
4y-3 = 54
4y=57
<u>y= 14.25</u>
