Answer:
-13
13
Step-by-step explanation:
Find the square root of the number 169 and use the positive and negative forms.
Follow order of operations.
Distribute what is in the parentheses.
4[6a^2 -2ab +3ab] + 5[3ab + 6b^2 -4ab]
Combine like terms in the brackets.
4[6a^2 + 3ab] + 5[-1ab + 6b^2]
Distribute the 4 and the 5.
24a^2 + 12ab -5ab + 30b^2
Combine like terms.
24a^2 +7ab + 30b^2
That's your final answer:
24a^2 +7ab + 30b^2

Answer:
y = -3x + 1
Step-by-step explanation:
Starting with the point (-1, 4) and the slope m = -3, write out the point-slope equation of a straight line: y - k = m(x - h) becomes y - 4 = -3(x + 1), or:
y = -3x - 3 + 4
y = -3x + 1 This is the same as answer choice (b).
