We want to see which one of the given expressions demonstrates the distributive property.
The correct option is the last one:
4*(2a + 3) = 8a + 12
The first thing we need to do is define the distributive property. It can be written as:
A*(B + C) = A*B + A*C
Now let's apply this to the given expression:
4*(2a + 3) = 4*(2a) + 4*3 = 8a + 12
Then we have:
4*(2a + 3) = 8a + 12
This is what we can see in the fourth option, then the correct option is the fourth one (counting from the top):
4*(2a + 3) = 8a + 12

B) yes, by SAS criterion
C) yes, by SSA criterion
D) no, not possible to tell.
Answer:
ΔABE ~ ΔCDE by AA criterion .
Option (A) is correct .
Step-by-step explanation:
As given
∠BAE = 45° and ∠CED = 70°
Now in the ΔABE .
By apply angle sum property of a triangles .
∠ABE + ∠BEA + ∠BAE = 180 °
(As ∠BAE = 45° , ∠ABE = 65°)
65 + ∠BEA + 45 = 180 °
∠BEA = 180° - (65+45)°
∠BEA = 180° - 110°
∠BEA = 70°
As in ΔCED .
∠CDE + ∠DEC + ∠ECD = 180°
(As ∠CED = 70° , ∠CDE = 65°)
65 + 70+ ∠ECD = 180°
∠ECD = 180° - (65+70)°
∠ECD = 180° - 135°
∠ECD = 45°
Now in the ΔABE and ΔCDE .
(1) ∠BAE =∠ECD = 45°
(2) ∠BEA=∠CED = 70°
(3) ∠ABE = ∠CDE = 65°
Thus ΔABE ~ ΔCDE by AA criterion .
Option (A) is correct .
It would take 8 weeks for them to have the same amount in the bank.
$148 +$8 every week: $260 -$6 every week:
Week 1: $156 $254
Week 2: $165 $248
Week 4: $180 $236
Week 6: $196 $224
Week 8: $212 $212
