Answer:

\left(a+3\right)\left(a-2\right)=a^2+a-6=

Step-by-step explanation:

Given expression is \left(a+3\right)\left(a-2\right).

Now we need to multiply this using FOIL.

F = First =\left(a\right)\left(a\right)= a^2

O = Outside =\left(a\right)\left(-2\right)= -2a

I = Inside =\left(3\right)\left(a\right)= 3a

L = Last =\left(3\right)\left(-2\right)= -6

Hence we get :

\left(a+3\right)\left(a-2\right)=a^2-2a+3a-6=a^2+a-6=

Answer:

(a+3)(a-2)=a^2+a-6

Step-by-step explanation:

The given expression is:

(a+3)(a-2)

Using FOIL, we multiply the;

First terms:a\times a=a^2

Outside terms: a\times -2=-2a

Inner terms:3\times a=3a

Last terms:3\times -2=-6

Putting all together we have:

(a+3)(a-2)=a^2-2a+3a-6

This simplifies to (a+3)(a-2)=a^2+a-6

A tourist first walked 17km with a speed of v km/h. Then he hiked 12 km uphill with the speed that was 2 km/hour less than his o
ExtremeBDS [4]

Answer: t=\frac{17}{v}+\frac{12}{v-2}


Step-by-step explanation:

Given: A tourist first walked 17km with a speed of v km/h.

Since Speed=\frac{distance}{time}

therefore, Time=\frac{distance}{speed}

Let t_1 be the time he walked with speed v.

then t_1=\frac{17}{v}

Also he hiked 12 km uphill with the speed that was 2 km/hour less than his original speed.

Let t_2 be the time he hiked 12 km,

Then t_2=\frac{12}{v-2}

The total time for the whole trip is given by:-

t=t_1+t_2=

Substitute the values of t_1 and t_2 in the equation, we get

t=\frac{17}{v}+\frac{12}{v-2}

Choose the ratios for sin A and cos A.
Irina18 [472]

Answer: D


Step-by-step explanation: By using SOH for sin A, 'S' being sin, 'O' being opposite side of angle A and 'H' being the hypotenuse which is the longest part of the triangle you would find that 15 is opposite from Sin A and 17 the hypotenuse, 15/17.

For cos A you would use CAH, C= cos, A which is the adjacent of the triangle located next to angel A which is 8, and H= hypotenuse (also note that the hypotenuse never changes even if the angle may be different) CAH would be cos A = 8/17

What is the measure of angle 6, if lines x and y are parallel, and angle 7 measures 121°? 121° 69° 59° 49°
Marianna [84]

Answer:

59°

Step-by-step explanation:

From the diagram, shown in the attachment line x and y are parallel lines.

Angle 7 and angle 6 are angles on a straight line.

The two angles will add up to 180 degrees.

\angle 7+\angle 6=180

But angle 7 measures 121°.

This implies that:

121+\angle 6=180

Solve for angle 6 to get;

\angle 6=180-121\

\angle 6=59\degree
