Well first off what do you think the answer is, ill check it and if its wrong then we will work from that
Answer:
Step-by-step explanation:
This is asking what is A
Formula A squared + B squared = C squared
A=x
B=8
C=20
X^2+ 8^2=20^2
8 squared is 64
20 squared is 400
400-64 is 336
X*X=336 find the square root of 336 =18.3
CHECK
18.3*18.3+ 8*8=398.89 which is super close to 400
Answer:
Solve the equation for x.
The simplified system is the arbitrary solution of the original system of equations.
Y=x+14
y=18−x2
Reorder 18
and −x2.
y=−x2+18
Y=x+14
Solve the equation for Y.
Y=−2y+50
x=36−2y
Reorder 36
and −2y.
x=−2y+36
Y=−2y+50
Step-by-step explanation:
Answer:
a = 8.7
Step-by-step explanation:
The Pythagorean theorem is
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2+5^2 = 10^2
a^2 +25 = 100
a^2 = 100-25
a^2 = 75
Taking the square root of each side
sqrt(a^2) =sqrt(75)
a =8.660254038
Rounding to the nearest tenth
a = 8.7
Answer:
A
Step-by-step explanation:
Hope this helps!
