Answer:
x = 2√5 and x = - 2√5
Step-by-step explanation:
x^2 = 20
x = 2√5 and x = - 2√5
3x10^8 is 7 times larger than 3x10^2
Multiply the equations to get the coefficients Greatest Common Factor:
3(2x+4y=11)
2(3x+6y=17)
6x+12y=33
6x+12y=34
Then you subtract them:
0x+0y=-1 0=-1
Or in other words no solutions
Answer:
74
Step-by-step explanation:
12 x 8 = 96
96 - 75% = 24
96 - 24 = 72
72 square inches will have grey paint
