NEED HELP IMMEDIATELY. I WILL BRAINLIEST. NEED TO SOLVE FOR X INTERCEPT

Kay [80]

Answer:

(1+√7,0),(1−√7,0)

Step-by-step explanation:

You can't factor the expression evenly, so use the quadratic formula.

a = 2

b= -4

c= -12

$\frac{-b+\sqrt{b^{2}-4ac } }{2a}$

$\frac{4+\sqrt{16{}-4(2)(-12)} }{2(2)}$

$\frac{4+\sqrt{16-4(-24)} }{4}$

$\frac{4+\sqrt{16+96} }{4}$

$\frac{4+\sqrt{112} }{4}$

$\sqrt{112} = 4\sqrt{7}$

End result: (1+√7,0),(1−√7,0)

you increase your walking speed from 1 m/s to 3 m/s in a period of 1 s. What is your acceleration? A) 2 m/s ^2 B) 3 m/s ^2 C) 5

arsen [322]

Acceleration is to change in speed divided by the time for the change. Change in speed is end speed minus started speed.

3m/s-1m/s and equals to 2m/s.

The answer should be A. (2m/s^2.)

Hope it helped you!

Have a great day!

an architect is presenting a scale model of a building she's designed to the planning committee of college the scale of the mode

Naddik [55]

The tall of the actual building will be 216 feet

Step-by-step explanation:

An architect is presenting a scale model of a building she's designed

to the planning committee of college

1. The scale of the model is 1 inch = 18 feet

2. The tallest wall in the model is 12 inches

3. We need to know how tall the actual building will be

Let us used the ratio method

∵ The scale of the model is 1 inch represents 18 feet

∵ The tallest wall in the model is 12 inch

→ Model(in) : Actual(ft)

→ 1 : 18

→ 12 : h

- By using cross multiplication

∴ 1 × h = 12 × 18

∴ h = 216 feet

∴ The actual height is 216 feet

The tall of the actual building will be 216 feet
