Answer is C.
3x and 4x² are not like terms, as their exponents do not share the same power (3x has a power of 1, 4x² has a power of 2)
Answer:
7.22 x 10^5
Step-by-step explanation:
Remember that the decimal is always to the right of the ones place.
1. Move it one place to the left and multiply by 10 to compensate.
2. Move it two places to left and multiply by 10^2.
3. Move the decimal point three times and multiply 10^3 to compensate, and the pattern continues until you reach the very last digit, the 7.
4. Numbers after the 7 that are not zeros will be after the decimal point.
so, 7.22 x 10^5
Answer:
1= -15 °C
2= 7 minutos y medio
Step-by-step explanation:
1= colo la temperatura va bajando 2 grados cada minuto lo único que hay que hacer es restarle 30 °C a 15 y nos da -15 ° C
2= Solo divides 15 entre 2 y ya.
3.1 is like a example when it is hiding a zero behind it and you find this when you do a math problem and you don't put zero in front of a number like 100-89 you don't write "011" so that is why it is like that
3 (x+7)
multiply 3 to both x and 7
3x+21
