I'm not sure if this question was correctly transcribed but is it suppose to read find if x=15, find y = 6x+30 ?
If so then y = 120
The way it is written now, If x = 15 then 6x cannot equal 30 which is why I asked. Sorry if I'm not understanding the question.
Answer:
(4y + 1)(2y + 1) -- Unfortunately I can't help with the grid part
Step-by-step explanation:
Multiply the a and c term (8 * 1) to get 8. Think of what factors of 8 would add up to your b term (6), which would be 4 and 2. Rewrite your equation as 8y^2 + 4y + 2y + 1 and consider one half at a time and factor them individually. For the left, that'd be 4y(2y + 1), and for the right, you can't factor anything so it's just 1(2y + 1). Check that the things inside the parentheses are the same, which they are, and add the things you factored out and multiply that by the part in the parentheses for (4y + 1)(2y + 1).
Simply solve the square.
(X^2-6)^2
Reorder the terms: 6.25 + -5y + y^2 = -14 + 6.25
Combine like terms: -14 + 6.25 = -7.75 6.25 + -5y + y2 = -7.75
Factor a perfect square on the left side: (y + -2.5)(y + -2.5) = -7.75
Can't calculate square root of the right side (negative). The solution to this equation could not be determined.
Answer:
Below in bold.
Step-by-step explanation:
The 3 angles add up to 180 degrees as they are in a triangle.
So 10x - 33 + 4x - 19 + 100 - 2x = 180
12x = 180 + 33 + 19 - 100
12x = 132
x = 11.
So the 3 angles are
10(11) - 33 = 110 - 33 = 77 degrees
4(11) - 19 = 25 degrees
100 - 2(11) = 78 degrees
