Answer:
6a³
Step-by-step explanation:
a⁴ + 9a³ - 10a² + 8a⁴ + X + a = 9a⁴ + 15a³ - 10a² = a
9a⁴ + 9a³ - 10a² + X + a = 9a⁴ + 15a³ - 10a² = a
9a³ + X + a = 15a³ = a
6a³ = X
checking: a⁴+ 8a⁴ + 6a³ = 15a³
9a⁴= 9a³
= a
Answer:
10 feet
Step-by-step explanation:
18 × 2 = 36
56 - 36 = 20
20 ÷ 2 = 10
To check work, add all lengths together. 4 sides. 18 + 18 + 10 + 10 = 56
Okay i believe the first one is 4/7 and the second one is 2. also don’t listen to them. sometimes it can be hard and you start to stress. good luck and if this isn’t right i’m so sorry :) keep your head up!!!
For points (x1,y1) and (x2,y2)
the slope is (y2-y1)/(x2-x1)
(3,4) and (6,6), slope is (6-4)/(6-3)=2/3
(4,-4) and (2,-7), slope is (-7-(-4))/(2-4)=(-7+4)/(-2)=-3/-2=3/2
for ax+by=c
slope=-a/b
3x+4y=12
slope=-3/4
