Answer:

The required expression is -c^2(3c-2)=-3c^3+2c^2

Step-by-step explanation:

Given : Expression -c^2(3c-2)

To find : Multiply the given expression?

Solution :

Step 1 - Write the expression

-c^2(3c-2)

Step 2 - Apply the distributive property a(b+c)=ac+bc

=-c^2\times 3c-2\times(-c^2)

Step 3- Multiply

=-3c^3+2c^2

Therefore, The required expression is -c^2(3c-2)=-3c^3+2c^2

Two diameters of circle P are AB and CD. Find the measure of arc ACD and arc AC when arc AD has a measure of 20 degrees
steposvetlana [31]

Answer:

Hence measure of arc ACD and arc AC are 340 degrees and 160 degrees respectively.

Step-by-step explanation:

Given:

A Circle with p as center and AB and CD as 2 diameters for a circle.

To Find:

Measure of ACD, and arc AC when arc AD is 20 degrees.

Solution:

<em>As we know that , Diameter is biggest chord which passes through center of circle,</em>

<em>Hence it divides the circle into two equal parts and making center as midpoint of it</em> .

(Refer the attachment)

angle APD=20 degree or arc AD=20 degree.

So AB as diameter ,so  arc DB=160 degree  or BPD=160 degree as A-B-P are

and angle APD and BPC are vertical opposite angles so they are congruent BPC=20 degree

Now,

points A,C,B,D,A makes circle which measures 360 degrees.

to find ACD

measure of ACD=360-(meaure of arc AD or angle APD)

=360-20

=340 degree.

Now arc AC,

as AB is diameter with p as midpoint ,A-P-B

arc APB=180 and arc BC=20 or angle BPC=20 degrees.

For measure of arc AC= measure of arc APB- arc BC

arc AC=180-20 degrees.

arc AC=160 degrees.

What's the area of this yellow surface? pick one of the options.
Oksi-84 [34.3K]
28 in^2

Divide shape into one rectangle and two squares:

Area of rectangle:
10 x 2 = 20 in^2

Area of one square:
2 x 2 = 4 in^2

Multiply that by 2 because we have 2 squares similar in size:
4 in^2 x 2 = 8 in^2

Add the area of the rectangle and two squares:
20 in^2 + 8 in^2 = 28 in^2

Have a nice day

Pls help I’m failing asap
Kryger [21]

Answer:

The equation 2d + 18 = 24 can help find the number of days Jerry has been doing sit-ups.

Step-by-step explanation:

During the first day, Jerry did 18 sit-ups, and he proceeded to do 2 more sit-ups each following day, so the expression to represent this situation is 2d + 18. Because he did 24 sit-ups today, to find the number of days he did sit-ups, the equation to solve is 2d + 18 = 24.
