Answer:
1.) step No.3 x(2x-5) - (2x-5)
2.) 16 +28i-28i - 49i²
but we know i² = -1
the expression becomes
16 + 49
= 66
Answer: (-2, 2) and (4, 8)
There are two solutions because the two functions cross each other twice.
Answer:
I'm thinking it's going to be C. 6 units
Step-by-step explanation:
Answer:
See answers below
Step-by-step explanation:
Since both trinagles asre similar hence the ratio of the similar sides are equal.
From both triangles;
y + 7 = 3y - 7
y - 3y = -7-7
-2y = -14
y = 14/2
y = 7
FE = 3y - 17
FE = 3(7) - 17
FE = 21 - 17
FE = 4
AB = y'+7
AB = 7 + 7
AB = 14
Similarly
3x+20 = 5x - 80
3x -5x = -80-20
-2x = -100
x = 100/2
x = 50
<A = 3x + 20
<A = 3(50) + 20
<A = 150 + 20
<A = 170degrees
Hence x= 50 and y = 7
