Step-by-step explanation:
Look at the picture.
Answer:
4x² + 22x − 1 = 0
Step-by-step explanation:
Start off with the standard formula to finding area with polynomials and quadratic functions.
(2x + 5)(2x + 6)
Work out like a normal binomial.
4 + 22x + 30 - 31
(You're subtracting 31 to take out the minimum of what the frame has to be)
4 + 22x - 1 = 0
Okay, for this proof, I'll write the steps out.
Statements:
1. ABCD is a parallelogram
2. FG bisects DB
3. <GEB ≡ (pretend congruent symbol) <FED
4. DE ≡ BE
5. <CDA ≡ <ABC
6. < CDB ≡ <DBA
7. triangle DFE ≡ triangle BGE
8. FE ≡ GE
9. DB bisects FG
Reasons:
1. Given
2. Given
3. vertical angles are congruent
4. If bisected, then split into congruent parts
5. opposite angles of a parallelogram are congruent
6. Subtraction Property
7. ASA
8. CPCTC
9. segment split into congruent parts by other segment is bisected.
Hope this helped! :)
Given:
Number of blue marbles, twice as many red marbles as blue, and 8 yellow marbles.
She has a total of 32 marbles.
To find:
The number of red marbles.
Solution:
Let number of blue marbles be x.
Then, number of red marbles = 2x
Number of yellow marbles = 8
Total number of marbles = 32




Now,
Number of red marbles 
Therefore, there are 16 red marbles.
