this is so complicated omdsss. surely someone help? I’ll brainlist you i promise!

1) The length and width of a rectangle is 3e + 2 and 3e - 2 respectively. Write the area of the rectangle in expanded form.

2) Expand and simplify.
3(a - 4) - 2(a + 7)

3) a. Expand 5(d - 3)
b. Use your answer from part (a) to simplify. 5(d - 3) + 2d + 10.

Answer:

here's your answer hope it helps you

Step-by-step explanation:

1. area of a rectangle=length*breadth

area=(3e+2)*(3e-2)

area=9e+2*-2

area=9e.

2. 3(a-4)-2+a+7)

3a-12-2(a+7)

3a-12-2(a+7)

3a-12-2a-14

3a-12-2a-14

3a-26-2a

1a-26

a-26 is the answer.

2. 5(d-3)+2d+10

5d-15+2d+10

5d-5+2d

7d-5

7d-5 is the answer.

Hawwa

1.) (3e +2)(3e -2) area of rectangle ( l×b)

use foil to expand ( first, outter, inner, last)

(3e + 2)(3e -2)

=9e -6e +6e -4

2) 3(a - 4) - 2 (a + 7)

= 3a -12 -2a -14

= 1a - 26

= a - 26

3.) a.] 5(d - 3)

= 5d - 15

b.] 5(d - 3) + 2d +10

= 5d -15 + 2d +10

= 7d -5

i hope they all right.
