The answer Would be 1 or incase infinite solution
Answer:
DP = 9/5
Step-by-step explanation:
DP + PE = DE
DP: x
PE: 4x + 7
DE: 10x - 2
x + 4x + 7 = 10x - 2
5x + 7 = 10x - 2
-5x = -9
x = 9/5
DP: 9/5
PE: 4(9/5) + 7
DE: 10(9/5) - 2
Check:
9/5 + 4(9/5) + 7 = 10(9/5) - 2
1.8 + 7.2 + 7 = 18 - 2
16 = 16
2a^4-3b^3
2*-2^4-3*3^3
2*16-3*9
32-27
5
Hope this helps :)
