Answer:

x^2 + 10x - 24 = 0

Step-by-step explanation:

Two zeros are 2 and -12:

  1. x - 2 = 0
  2. x + 12 = 0

So the function is (x-2)(x+12) = 0

<=> x^2 + 12x - 2x - 24 = 0

<=> x^2 + 10x - 24 = 0

Triangle ABC IS an isosceles triangle AB=BC m
True [87]

Answer:

<em>The measure of angle A is 73°</em>

Step-by-step explanation:

<u>Isosceles Triangles</u>

An isosceles triangle is a triangle with exactly two congruent sides. The angles the congruent sides form with the third side are also equal.

The triangle ABC is isosceles and AB congruent with BC. The angle at B measures 34°.

The other two angles are congruent, i.e. their measures are the same. Since the internal angles of a triangle sum 180°:

2*m\angle A=180^\circ - 34^\circ =146^\circ

Thus:

m\angle A=146^\circ /2=73^\circ

The measure of angle A is 73°

lisabon 2012 [21]

Answer: 1249 hrs

Step-by-step explanation:

Sophia walked for 12 km to get to her aunt's house.

She did this at a speed of 5km/h which means that the time taken was:

Time = Distance / Speed

= 12 / 5

= 2.4 hours

2.4 in hours:

= 0.4 * 60 minutes

= 24 minutes

= 2 hours 24 minutes

If she left at 1025, she would arrive at:

= 1025 + 2 hours 24

= 1249 hrs

What is the value of 6(2b-4) when b =5
Sindrei [870]

Answer: The value of 6(2b-4) is 36.


Step-by-step explanation:

Given expression: 6(2b-4)

To find the value of 6(2b-4) at b= 5, we need to substitute the b=5 in the expression, we get

6(2(5)-4)\\=6(10-4).......[\text{solve parentheses}]\\=6(6)\\=6\times6=36

\\\Rightarrow6(2(5)-4)=36

Therefore, the value of  6(2b-4) is 36, when b=5.
