Answer:
x = 5
Step-by-step explanation:
a² + b² = c²
x² + 12² = 13²
x² + 144 = 169
x² = 169 - 144
x² = 25

x = 5
10*30=300
10*4=40
6*30=180
6*4=24
add them up: 300+40+180+24=544

Answer:
-3x + 4y = 40.
Step-by-step explanation:
Let's convert the equation to standard form:
y - 4 = 3/4(x + 8)
y - 4 = 3/4 x + 6
y = 3/4x + 10
Multiply through be 4:
4y = 3x + 40
-3x + 4y = 40 (answer).
