7x - 4y = -28
3x +4y = -12
Using the elimination method because y is already eliminated
10x = -40
So x = -4
Then plug the -4 into the first equation....
7(-4) - 4y = -28
-28 - 4y = -28
-4y = 0
y = 0
I got: -4,0
Answer: 
Step-by-step explanation:
Given

HI=88 ft
IJ=62 ft
From the figure, we can write

Answer:
(g + 4)(g + 10)
Step-by-step explanation:
Note that 10*4 = 40 (which is the constant in g^2 + 14g + 40) and that 10 + 4 = 14 (which is the coefficient of x in g^2 + 14g + 40).
Thus, g^2 + 14g + 40 factors into (g + 4)(g + 10) (second answer choice).
Answer:
24.89
Step-by-step explanation:
sin 40 = 16/x
x = 16/sin 40
x = 24.89
