Answer:
x = 2 or x = -2
Step-by-step explanation:
5x² - 15 = 5
⇌
5x² = 15 + 5
⇌
5x² = 20
⇌
x² = 20/5 = 4
⇌
x² = 2²
⇌
x² - 2² = 0
⇌
(x - 2)(x + 2) = 0
⇌ we use the zero product property
x - 2 = 0 or x + 2 = 0
⇌
x = 2 or x = -2
Answer:
Lengths to be added are converted into cm.
15 m 18 cm = 1500 cm + 18 cm = 1518 cm
16 m 22 cm = 1600 cm + 22 cm = 1622 cm
Now, sum
1 1
1518 cm
+ 1622 cm
3140 cm
= 31 m 40 cm
Therefore, 15 m 18 cm + 16 m 22 cm = 31 m 40 cm
