Answer:
the answer is A
Step-by-step explanation:
the Pythagorean theorem is a squared + b squared = c squared (c always being the hypotenuse and a and b being the legs. 2 (4) squared pus 10 (100) squared=104 then you would use the square root of 104. 104 does not have a whole number square so the answer is 
3x^2-18x+24
3(x^2-6x+8)
3(x-4)(x-2)
I think the answer is (10,5)
Answer:
x=-0.21...
Step-by-step explanation:
Make the expression equal 0
32x+1-3x+5=0
Combine the x terms
29x+1+5=0
Combine the constants
29x+6=0
Isolate the x term
29x=-6
Isolate the variable
x=-0.21...
(I rounded to the nearest 100th)
Das is disguised pythagorean theorme
the height is one leg
the distance from house is other leg
length of ladder=hyptoonuse
so
remmeber
if legs of right triangle are a and b and hyptonuse is c then
a²+b²=c²
so
legs are 15 and 20
15²+20²=c²
225+400=c²
625=c²
sqrt both sides
25=c
25ft is length of laddder
