Answer:

Step-by-step explanation:

the product is a result of multiplication....so lets multiply

x^2 (x^4 + x^2 - 1) =

x^6 + x^4 - x^2

ok...his mistakes are occurring because he is multiplying the exponents when he is supposed to be adding them.

exponent rule : x^a * x^b = x^(a + b)

Square OABC is drawn on a centimetre grid. O is (0,0) A is (2,0) B is (2,2) C is (0,2) Write down how many invariant points ther

ANTONII [103]

Answer:

There is one point: A (x, y) = (2, 0)

Step-by-step explanation:

A point of the square OABC is invariant only if its location coincides with location of the rotation axis, that is, that such point experiments only rotation, no translation in any form. The center of rotation coincides with the location of one of the vertices of the square and, therefore, there is one invariant point on the perimeter: A (x, y) = (2, 0)

emmasim [6.3K]

Answer:

according to my calculation Lucita's estimate is too low.

Step-by-step explanation:

because if we divide 3.302 by -1.27 we get -2.6 but lucita wrote 0.026

so it means that she wrote is so low it has to be bigger

hope i helped

can i have brainliest plss
