90+1/3x-30+120=x怎麼解方程

90+1/3x-30+120=x
180+1/3x=x
2/3x=180
x=180÷2/3
x=180×3/2
x=270

歸納長方形，正方形，三角形，梯形，平行四邊形，圓柱的面積公式，以及長方體，正方體，圓柱體，圓錐的體

S長方形：長*寬
S正方形：邊長^2
S三角形：（底*高）/2
S梯形：（上底+下底）*高/2
S平行四邊形：底*高
V柱：底面積*高
V正方體：棱長^3
V長方體：長*寬*高
V錐：1/3*底面積*高

已知tan=3，求（3sina-cosa）/（sina+3cosa）的值

上下同除以cosa
由sina/cosa=tana
所以原式=（3tana-1）/（tana+3）=4/3

（x+7/x+6）+（x+9/+x+8）=（x+10/x+9）+（x+6/x+5）

（x+7/x+6）+（x+9/+x+8）=（x+10/x+9）+（x+6/x+5）
（x+9/+x+8）-（x+10/x+9）=（x+6/x+5）-（x+7/x+6）
（（（x+9）^2-（x+8）（x+10））/（（x+8）（x+9）））=
（（（x+6）^2-（x+5）（x+7））/（（x+5）（x+6）））
（（（x+9）^2-（x+9-1）（x+9+1））/（（x+8）（x+9））=
（（（x+6）^2-（x+6-1）（x+6-1））/（（x+5）（x+6））
（（（x+9）^2-（x+9）^2+1）/（（x+8）（x+9））=
（（（x+6）^2-（x+6）^2+1））/（（x+5）（x+6））
（1/（（x+8）（x+9））=（1/（（x+5）（x+6））
（x+8）（x+9）=（x+5）（x+6）
x^2+17x+72=x^2+11x+30
11x+30=17x+72
x=-7

關於X的二次函數F（X）=1/aX^2-4X+1（0

這個是看對稱軸在（0,1）離哪一個端點近一點，如果小於1/2，離0近，那說明最大值在1這個點，反過來同理.

已知一次函數y=（m-3）x+2m-1的圖像進過第一，二，三象限，求m的取值範圍

y是一次函數，且經過第一，二，三象限
那麼斜率是正的，也即：m-3>0，m>3
且和y軸的交點在正半軸上，也即：2m-1>0，m>1/2
所以m>3
