Jakob simplified the expression as shown.
(6.7x-.4x--2)
6.7x-3-3.4x-1-2x-2
(6.7x-3.4x-2x)+(-3-1-2)
1.3x-6
what was jakob's error in subtracting the expressions?
o he used the commutative property incorrectly.
he used the distributive property incorrectly.
o he used the associative property incorrectly.
he simplified the x coefficients incorrectly.

What number should be added to both sides of the equation to complete this square? x^2-10x=7

Me complete this proof! prove that a quadrilateral is a square. me with the steps for this proof.

Stefano accidentally dropped his sunglasses off the edge of a canyon as he was looking down. the height, h(t), in meters (as it relates to sea level), of the sunglasses after t seconds, is shown in the table. during its descent, the pair of sunglasses passed by a climber in the canyon 6 seconds after stefano dropped them. to the nearest meter, what is difference in elevation between stefano and the climber? 166 meters 176 meters 230 meters 240 meters its b.176 i took the test 166 is wrong and 176 is correct
