Answer:
x = ± 2
Step-by-step explanation:
Given
16 - 2x² = - 64 ( subtract 16 from both sides )
- 2x² = - 80 ( divide both sides by - 2 )
x² = 40 ( take the square root of both sides )
x = ± 
= ± 
= ± 2

Step-by-step explanation:
Answer:
m∠J = 67°
m∠T = 67°
m∠G =46°
ST = 5cm
HJ = 3.7cm
Step-by-step explanation:
Given
- GH = 5 cm = GJ
- m∠GHJ = 67°
=> m∠J = 67° ( that is the property of isosceles triangle because GH = GJ
=> m∠G = 180° - m∠H - m∠J = 180° - 67° - 67° = 46°
=> GH = GJ = ST =SU
=> ST = 5 cm
- Because ΔGHJ ≅ ΔSTU and GH = GJ = ST =SU
=> TU = HJ = 3.7 cm
=> m∠T = m∠H = 67°
So:
m∠J = 67°
m∠T = 67°
m∠G =46°
ST = 5cm
HJ = 3.7cm
Example answers:
1) -8x + 66
2) -2(5x+10) -2(-3x+8)
Answer:
16=18
Step-by-step explanation:
2x-5x+16
-3x+16
-3(x-6)
-3x+18
-3x+16+-3x+18
16=18
-they do not share the same answer
and if you where to keep going
18-16=2
0=2
-so again not equal
hope that helps
