Answer:
2.8
Step-by-step explanation:
1.4 is AE correct?
Well then, BD is twice the length of that, so multiply by 2 to get 2.8.
Answer:
<u>x = √13 - 3</u>
<u>x = -√13 - 3</u>
Step-by-step explanation:
Given :
Solving :
- x² + 6x + 9 - 9 - 4 = 0 [Adding and subtracting 9]
- (x + 3)² - 13 = 0 [Group the square term together]
- (x + 3)² -13 + 13 = 0 + 13 [Add 13 on both sides]
- √(x + 3)² = √13 [Taking square root on both sides]
- x + 3 - 3 = ±√13 - 3 [Subtract 3 from both sides]
- x = ±√13 - 3
Solutions :
- <u>x = √13 - 3</u>
- <u>x = -√13 - 3</u>
Answer:
- 19
Step-by-step explanation:
2q - p ( substitute p = 3, q = - 8 into the expression )
2(- 8) - 3
= - 16 - 3
= - 19
It’s the second it’s repeated addition
