The answer to "12x-(4y+7z) for x=9 y= 4 and z = 2" is 78.
Answer:
220 squared units
Step-by-step explanation:
first, find the area of the rectangle by multiplying 8 by 20. Then, fin the area of the triangle by multiplying 6 by 20 and then dividing the result by 2.
8*20=160
6*20=120
120/2=60
Finally, add them together and you get 220 units squared.
10 1/3= 31/3
31/3= 93/9
11 5/9= 104/9
93/9 + 104/9 = 197/9
197/9= 21 8/9
your answer is 21 & 8/9

Take 49 and divide it by 7 and you get 7. 7 times 10 is 70. Your answer is $70.
Answer:
b. y = 3(x+2)^2 + 5
Step-by-step explanation:
The vertex form of a parabola is
y = a(x - h)^2 + k where (h, k) is the vertex.
Here h = -2 and k = 5 so the following could be the required equation\;
y = 3(x+2)^2 + 5
