3 multipled by square root of 2 cm.
- × 9x = -9x
- × +8 = -8
-9x - 2x = -11x
-8 - -10 = +2
answer = -11x +2
Answer:
70 m²
Step-by-step explanation:
Red sides:
2 x ( 5 x 5 ) = 2 x 25 = 50
Blue side :
2 x ( 1 x 5) = 2 x 5 = 10
Green :
2 x ( 1 x 5 ) = 2 x 5 = 10
Total surface area:
50 + 10 + 10 = 70
Units : m²
Surface Area = 70 m²

Answer:
C
Step-by-step explanation:
Given
x² - 10x + 24 = 0
Consider the factors of the constant term (+ 24) which sum to give the coefficient of the x- term (- 10)
The factors are - 4 and - 6, since
- 4 × - 6 = + 24 and - 4 - 10 = - 10, hence
(x - 4)(x - 6) = 0 ← in factored form → C
