Answer:
4x^2 − 4x −1 + 11 / x+1
Step-by-step explanation:
The answer is
4x^2 − 4x −1 + 11 / x+1
Answer:
i) not similar but corresponding angles have equal measures.
the blue object required to be dragged to the box is the fourth object which is a square. A square will not have proportional lengths and is not similar to the given figure but the corresponding angles will have equal measures.
ii) not similar but side lengths are proportional.
the blue object required to be dragged to the box is the first object which is a parallelogram. A parallelogram will have proportional lengths and is not similar to the given figure because the corresponding angles do not have equal measures.

Answer:
(a) -20 1/2
Step-by-step explanation:
The proportion can be solved using "cross multiply" as the first step. This eliminates the fractions and turns it into a linear equation.
2/7 = -5/(x +3) . . . . . given
2(x +3) = -35 . . . . . . multiply by 7(x +3)
2x = -41 . . . . . . . . . simplify, subtract 6
x = -20 1/2 . . . . . . divide by 2
Answer:
Scientists reached a decision about when to begin the experiment.
Explanation:
Changing of a sentence from passive to active voice or vice versa involves the situational changes in the sentence of both the subject and the object (if there are any). From the example given in the question, the sentence in the passive voice is-
<u><em>A decision was reached by scientists about when the experiment would begin.</em></u>
To change this sentence into an active voice, the identification of the subject and object is needed. And then, in an active voice, the subject will be at the beginning of the sentence.
'<u><em>Decision</em></u>' is the object in the sentence while the '<em><u>scientists</u></em>' signify the subject(s).
Thus, the new sentence in the active voice will become-
Scientists reached a decision about when to begin the experiment.
