10a * (a + 2)
Factor completely and check mentally 10a^2+20a
It cannot be simplified any further, so it is: 5a³ + 15a² + 20a
20a plus 14 will be 34a minus 8a minus 7 34a minus 8 is 26a minus 7 is 19a. The single b is 1b plus 6b which is 7b minus 2b equals 5b.
To determine the factors of the terms in the expression (20a + 15ab + 24b), we can factor each term. The factors of (20a) are (4 \times 5 \times a), the factors of (15ab) are (3 \times 5 \times a \times b), and the factors of (24b) are (3 \times 8 \times b). Common factors among the terms include (3) and (b). Thus, any statements indicating these common factors or the individual factors of each term would be true.

20a^2
Factor completely and check mentally 10a^2+20a
It cannot be simplified any further, so it is: 5a³ + 15a² + 20a

5(4a + 7)
20a plus 14 will be 34a minus 8a minus 7 34a minus 8 is 26a minus 7 is 19a. The single b is 1b plus 6b which is 7b minus 2b equals 5b.
It is 20a - 5b - 9.
As written, that equals 32a - 8, which factors to 8(4a - 1) If you meant 20a^2 + 12a - 8, that factors to 4(5a - 2)(a + 1)

20a + 45 = 5(4a + 9)
To determine the factors of the terms in the expression (20a + 15ab + 24b), we can factor each term. The factors of (20a) are (4 \times 5 \times a), the factors of (15ab) are (3 \times 5 \times a \times b), and the factors of (24b) are (3 \times 8 \times b). Common factors among the terms include (3) and (b). Thus, any statements indicating these common factors or the individual factors of each term would be true.
To calculate the watts from amperes and volts, you can use the formula: Watts = Amperes × Volts. For 20A at 110V, the calculation would be 20A × 110V = 2200 watts. Therefore, 20A at 110V is equal to 2200 watts.
