Answer: The identity is verified. See the explanation.
Step-by-step explanation:
You must keep on mind the following identities:
Therefore, by substitution, you can rewrite the identity as shown below:
Simpliying, you obtain:
The identity is verified.
In these types of problems, the first step is to combine like terms. Like terms are terms with the same exponent (power), and the same variable (like all x's). In the above equation, we can combine -5x, 2x and -3y. Let's do it:
The next step would be to factor out the common ratio, which is not applicable here, so your answer would be
-6x + 7y. Hope this helps!
Short Answer: B
Remark
The area of any triangle is
A = 1/2 b * h
b = 7 3/4
h = 4 2/3
Step one
Convert all fractions to improper fractions.
7 3/4 = (28 + 3) / 4 = 31/ 4
4 2/3 = (12 + 2) / 3 = 14/3 Now multiply
Step Two
Multiply
Area = 1/2 * 31/4 * 14/3 Multiply the numerators together and then the denominators.
Area = (1 * 31 * 14) / (2 * 4 * 3) = 434 /24
Step 3
Convert this to a whole number + a fraction
Area = 18 + 0.08333333 You already have your answer. It is B because only B gives an answer of 18. But you can get the rest of
Let x = 0.083333333
100 x = 8.3333333333
<u>x = 0.0833333333 </u> Subtract
99 x = 8.25 Divide by 3 on both sides.
33 x = 2.75 Divide by 11
3x = 0.25
x = 0.25/3 Multiply top and bottom by 4
x = 1 / 12
The answer is 18 1/12.
Answer:
#5
Area = Area of bigger triangle - Area of small triangle
#8
Area = area of square + area of two right angled triangles
I believe your answer would be B, Bisect AB, but not be perpendicular to it.
