I think its the first answer choice
Answer:
y=x^2+8x+13
Step-by-step explanation:
in standard form
y=x^2+8x+13
4:6 x:18
Lets solve for x
Cross multiply
4*18 = 72
6*x = 6x
6x = 72
6x/6 = 72/6
x = 12
Answer: x = 12
4(5a-8) = 20a - 32. 20a - 32 + 2a = 22a - 32, which is not equal to 12a - 6. Mary is wrong.
Answer:
24
Step-by-step explanation:
Plugin the value of x and y
8[x + y] = 8*[5 - 2]
= 8 *3
= 24
