Answer:
10.4
Step-by-step explanation:
We can use the Pythagorean theorem to solve for the unknown side since this is a right a triangle.
a^2 +b^2 =c^2
where a and b are the sides and c is the hypotenuse
6^2 + x^2 =12^2
36+x^2 = 144
Subtract 36 from each side
36-26+x^2 =144-36
x^2 =108
Take the square root of each side
sqrt(x^2) = sqrt(108)
x = sqrt(108)
x =10.3923
x =10.4 rounding to the nearest tenth
Answer:
-xz - 2x²- 2yz
Step-by-step explanation:
Multiply out (x-2y)z-2x(x+z)
(x - 2y)z - 2x( x + z)
Rearrange
z(x - 2y) - 2x(x + z)
Open bracket by multiplying by letters outside bracket
xz - 2yz - 2x² - 2xz
Collect like terms
xz -2xz - 2x² - 2yz
-xz - 2x² - 2yz

Answer:you solve on each sides like normal then your equation will come out as “not a solution”
Step-by-step explanation:
13=-7
replace the numbers inside () for x
f(4) = -4(4)-3 = -16 -3 = -19
G(-4) = 2(-4)^2 -3(-4) = 44
