Ta có bảng
x+5 | 25 | 1 | -1 | -25 | 5 | -5 |
y-5 | 1 | 25 | -25 | -1 | 5 | -5 |
x | 22 | -4 | -6 | -30 | 0 | -10 |
y | 6 | 30 | -20 | 4 | 10 | 0 |
(x+3).(y-5)=25
Ta có:các số nhân nhau bằng 25 là:5x5
=>x+3=5 và y-5=5
x=5-3 y=5+5
x=2 y=10
Vậy:x=2;y=10 chúc bạn học tốt

It's a truth that in love and war,
World's collide and hearts get broken,
I want to live like I know I'm dying,
Take up my cross, not be afraid
[Chorus]
Is it true what they say, that words are weapons?
And if it is,then everybody best stop steppin',
Cause I got ten in my pocket that'll bend ya locket,
I'm tired of all these rockers sayin' come with me,
Wait, it's just about to break, its more than I can take,
Everything's about to change,
I feel it in my veins, its not going away,
Everything's about to change.
It creeps in like a thief in the night,
Without a sign, without a warning,
But we are ready and prepared to fight,
Raise up your swords, don't be afraid,
[Chorus]
This is a warning, like it or not,
I break down, like a record spinning,
Gotta get up,
So back off,
This is a warning, like it or not,
I'm tired of listenin', I'm warning you, don't try to get up,
There's a war going on inside of me tonight (don't be afraid) [x2]
Wait, it's just about to break, its more than I can take,
Everything's about to change,
I feel it in my veins, its not going away,
Everything's about to change,
It's just about to break, its more than I can take,
Everything's about to change,
I feel it in my veins, its not going away,
Everything's about to change.

Gọi chiều dài, chiều rộng hình chữ nhật lần lượt là a,b (a>b>0) (m)
Theo đề, ta có
2a + 2b = 140 *
a = b + 10 **
Thay ** vào *, ta có :
2(b + 10) + 2b = 140
4b + 20 = 140 => b = 30 m
a = b + 10 = 40 m
4:
a: Xét ΔBAH vuông tại H và ΔBCA vuông tại A có
góc B chung
=>ΔBAH đồng dạng với ΔBCA
=>BA/BC=BH/BA
=>BA^2=BH*BC
b: ΔABC vuông tại A có AH là đường cao
nên HA^2=HB*HC
c:Sửa đề; Cắt AH tại D
DA/DH=BA/BH
EA/EC=BA/BC
=>DA/DH*EA/EC=BA/BH*BA/BC=1
