X^2−4x−21 I need help with this question and please right every step of it

Damm [24]

Answer:

<h3> $\boxed{ \boxed{ \sf{ \bold{( x - 7)(x + 3)}}}}$ </h3>

Step-by-step explanation:

$\sf{ {x}^{2} - 4x - 21}$

Here, we have to find the two numbers that subtracts to 4 and multiplies to 21

⇒ $\sf{ {x}^{2} - (7 - 3)x - 21}$

⇒ $\sf{ {x}^{2} - 7x + 3x - 21}$

Factor out X from the expression

⇒ $\sf{ x(x - 7) + 3x - 21}$

Factor out 3 from the expression

⇒ $\sf{x(x - 7) + 3(x - 7)}$

Factor out x-7 from the expression

⇒ $\sf{(x - 7)(x + 3)}$

Hope I helped!

Best regards!!

When leaving a town, a car accelerates from 30 kmh-1 to 60 kmh-1 in 5 s. Assuming the

aleksandr82 [10.1K]

Answer:

B .62.5 m

Step-by-step explanation:

convert Kmh-1 in to ms-1

30 Kmh-1 = (30×1000) ÷3600 = 8.3ms-1

60 Kmh-1 = (60×1000) ÷3600 = 16.6 ms-1

acceleration = (16.6 - 8.3) ÷ 5 = 1.66 ms-2

V^2 = U^2 +2aS

(16.6)^2 = (8.3)^2 + 2×1.66 ×S

S = 62.5 m
