Answer:

13.01d - 2.65

Step-by-step explanation:

DON'T IGNORE THIS PART!!!

Hmmm... in order to be able to solve these type of expressions and more complex ones, we need to know what like terms are in the first place.

Well, the best definition of like terms is: <u>Terms that have the same exact variables.</u>

<u />

Let's see the terms that have the same exact variables! They are 3.26d and 9.75d.

By the way, before we continue--I would like to mention something extremely important: 3.26d and 9.75d are positive, whereas -2.65 is negative (you know, the negative sign appears right before it).

Now, let's add 3.26d and 9.75d. It equals 13.01d.

TIME TO COMBINE!!!

13.01d - 2.65

Lerok [7]

Answer:


Step-by-step explanation:

TO prove this we have to prove one of following.

SSS ( all three sides are equal )

SAS ( two sides and their middle angle is equal )

ASA ( two angles and their middle side are equal )

I am proving both triangles equal by ASA method.

The complete proof and explanation is given in attachment below.

Let z1 = a1 + b1i, z2 = a2 + b2i, and z3 = a3 + b3i. Prove the folowing using algebra or by showing with vectors.
Svetlanka [38]

Answer:

a)z1 +z2 =z2 + z1 ...proved.

b) z1 + ( z2+ z3 )=(z1+z2)+z3 ... proved.

Step-by-step explanation:

It is given that there are three vectors z1 = a1 + ib1, z2 = a2 + ib2 and z3 = a3 + ib3. Now, we have to prove (a) z1 + z2 = z2 + z1 and (b) z1 + (z2 +z3) = (z1 + z2) + z3.

(a) z1 + z2 = (a1 +ib1) + (a2+ ib2) = (a1 +a2) + i(b1 +b2) {Adding the real and imaginary parts separately}

Again, z2 + z1 =(a2 +ib2) + (a1 +ib1) = (a2 +a1) + i(b2 +b1) {Adding the real and imaginary parts separately}

Hence, z1 +z2 =z2 + z1 {Since, (a1 +a2) = (a2 +a1) and (b1 +b2) = (b2 +b1)}

(b) z1 + ( z2+ z3 ) = [a1 + ib1] + [(a2 + a3 ) + i(b2 + b3 )] = ( a1 + a2 + a3) + i( b1+ b2+b3) {Adding the real and imaginary parts separately}

Again, (z1+z2)+z3 = [(a1+a2) +i(b1+b2)]+[a3+ib3] = ( a1 + a2 + a3) + i( b1+ b2+b3) {Adding the real and imaginary parts separately}

Hence, z1 + ( z2+ z3 )=(z1+z2)+z3 proved.

The perimeter of square is 24cm, find its<br>area<br>​
mihalych1998 [28]

Answer:

Answer is 36cm

Step-by-step explanation:

Given:-

The perimeter of a square is 24 cm

To Find:-

It's Area

Solution:-

One side of the square

=24/4cm

=6cm

We know that, formula of the area of a square,

Area=(one side)^2

so,the area of the square=6^2cm=36

Important formula:-

•Perimeter of square=4×one side

•Perimeter of rectangle =2(length+breadth)

•Area of rectangle=length×breadth

I hope it's helpful!
