Answer:
/65
Step-by-step explanation:
a²+b²=c²
c will always be the hypotenuse
4²+7²=65² the opposite of ² is square root so
/65
it doesn't want it answered so that's your final answer.
Answer:
x + 5 = -3
x=-10
2(3x - 8)
Step-by-step explanation:
1-
Multiply both sides of the equation by 5: 4x + 25 = -15
Move the constant to the right-hand side and change its sign : 4x = -15 - 25
Calculate the diffrerence: 4x = -40
Divide both sides of the equation by 4 : x= -10
2-
Collect like terms: 6x-4-12
Factor out 2 from the expression : 2(3x - 8)
Answer:
Step-by-step explanation:
Multiplying x+6y=-3 with 2 so its equal to first eqn,
Eliminating,
2x + 3y = 3 (1)
2x +12y = -6 (2) (because subtracting)
------------------
-9y =9
∴y=-1
eq. y in 1
2x -3=3
2x=3+3
x=6/2
=3
Pls mark me brainliest
There are at least two different things that could go in
the blank spot and make the equation a true statement.
It could be " - 2 " .
It could be " · 4/3 " .
It could be " + 2 cos(π) "
etc.
