If anyone knows the anwser pls tell me

Fudgin [204]

Answer:

z = 156

Step-by-step explanation:

y² = 65²-25² = 4225 - 625 = 3600

(x+25)²-65² = z²

x²+50x+625-4225 = z²

x²+50x-3600 = z² ....(1)

x²+60² = z²

x²+3600 = z² ....(2)

(1)-(2): 50x - 7200 = 0

50x = 7200

x = 144

check: x² + y² = z² 144² + 60² = 24336 = z² z = 156

(25+144)²-65² = z² = 28561 - 4225 = 24336 z = 156

Can somebody help me????

ddd [48]

$f(x)=5x^2-3\\\\\\
f(x+a)=5(x+a)^2-3=5(x^2+2ax+a^2)-3=\\\\=\boxed{5x^2+10ax+5a^2-3}$

On the other hand:

$f(x+a)=5x^2+30x+42$

so:

$10ax=30x\\\\10a=30\qquad|:10\\\\\boxed{a=3}$
