Idk about b but for c, you just show distribution method and do 3m times 2m (which equals 6m squared) and then 3m times -1 (=-3m) and then 7 times 2m is 14m and then7 times -1 is -7. OKAY so now that u have all that, you have: 6m^2-3m+14m-7. Now collect like terms. You end up getting 6m^2+11m-7 AND THATS YOUR ANSWER !!!
Answer:
Let 3x and 2x are divided into 250.
Step-by-step explanation:
3x + 2x = 250
⇒ 5x = 250
⇒ x = = 50
∴ 3x = 3 × 50 = 150 and
2x = 2 × 50 = 100
Thus, the required numbers are 150 and 100.
Answer:
Step-by-step explanation:
basically, you have to look at the inequality. it is the same all around. so if the inequality has less than or equal too, or greater than or equal too, you need to have a thick solid line representing your function. if it is just less than or greater than, use a dotted line. to determine whether the shading goes above or below, you look at the in equality. greater than is above, and less than is below
Answer:
PQR+SQR=180°(angles in a triangle)
75°+SQR=180°
SQR=180°-75°
SQR=105°
