Answer:

Step-by-step explanation:

1. P = (width + lengh) * 2 = (23 + 10) * 2 = 33 * 2 = 66

  A = width * lengh = 23 * 10 = 230

2. width = 7

 P = (width + lengh) * 2 = ( 7 + 9) * 2 = 16 * 2 = 32

Answer:

4. area= 230cm^2 perimeter= 66cm

5. width= 7m  perimeter= 32m

Step-by-step explanation:

4. a = w*l

23cm*10cm=230cm^2

p= add all sides

23cm+23cm+10cm+10cm=66cm

5. w= a/l

63m^2/9m=7m

p= add all sides

7m+7m+9m+9m=32m

Find missing angle measures
saw5 [17]

Answer:

∠ 1 = 160°, ∠ 2 = 20°

Step-by-step explanation:

The 2 angles are adjacent and supplementary, thus

∠ 1 + ∠ 2 = 180°, substitute values

5x + x - 12 = 180, that is

6x - 12 = 180 ( add 12 to both sides )

6x = 192 ( divide both sides by 6 )

x = 32

Thus

∠ 1 = 5x = 5(32) = 160°

∠ 2 = x - 12  = 32 - 12 = 20°

Please help me understand this​
Delvig [45]

The correct answer is 75% increase.

The number 4 to 7 is increasing not decreasing since the number is higher than before.

Also 4 x 0.75 = 3 and 4 + 3 = 7 so it’s and increase of 75%

Hope this helps.
