Answer: x=32
Exclamation:
-3x\4+25=1/8x-3
-3/4x+25=x/8-3
-6x+200=x-24
200=x-24+6x
200=7x-24
200+24=7x
224=7x
224/7=32
You can use the Pythagorean theorem, a^2+b^2=c^2, to solve this.
b= square-root of (c^2)-(a^2)
b= square-root of (9^2)-(2^2)
b= 8.77.... which in the exact form is square root of 77.
Answer:
(x+8)^2
Step-by-step explanation:
x^2 +16x+64
What two numbers multiply to 64 and add to 16
8*8 = 64
8+8 = 16
(x+8)(x+8)
(x+8)^2
Add -2y to both sides
3x+2y+-2y=-12+-2y
3x=-2y-12
Divide both sides by 3
3x/3=-2y-12/3
x=-2/3y-4
hope this helps!
