Answer:
the first one is 90, the second is 150, the third is option dStep-by-step explanation:
Answer:
x = −
4 ± √
10,
Step-by-step explanation:
2(x + 4)² = 20
=> 2(x + 4) (x + 4) = 20
=> 2x + 8 (x + 4) = 20
=> 2x² + 8x + 8x + 32 = 20
=> 2x² + 16x + 32 = 20
=> 2x² + 16x + 12 = 0
=> Now solve using the quadratic formula:
x = −
4 ± √
10,
Radical form: −
4 ± √
10,
Decimal form: -0.84, -7.16
