Answer:
if you want to sketch the trapezoid you will also need other dimensions like height and the length of the parallel sides
A and B could be any of these combos
1+23
2+22
3+21
4+20
5+19
6+18
7+17
8+16
9+15
10+14

Answer:
Step-by-step explanation:
Let's solve your equation step-by-step.
(y+4)(3y−5)=0
Step 1: Simplify both sides of the equation.
3y2+7y−20=0
Step 2: Factor left side of equation.
(3y−5)(y+4)=0
Step 3: Set factors equal to 0.
3y−5=0 or y+4=0
y=5
/3
or y=−4
Answer:
21
Step-by-step explanation:
let n be the identical number, then
n² = 441 ( take the square root of both sides )
n = 
= 21
The the identical numbers are 21
