Your answer would be -9 & -42.
Here's why ...
(-9)*(-42) A negative times a negative equals a positive (378).
Now, -9-42=-51 & you add these because you have two negatives.
Hope this makes sense & helps you ! (:
A.
y = 7 - |x| = 7 - 2 = 5
b.
y = x² - 1 = 2² - 1 = 4 - 1 = 3
c.
y = √(x + 14) = √(2 + 14) = √16 = 4

Answer:
of the lasagna is left
<u>Step-by-step explanation:</u>
Given:
Amount of lasagna Rico eats = 1/9
Amount of lasagna His friend eats = 1/18
To Find:
The amount lasagna is left =?
Solution:
Total lasagna ate by both Rico and his friend = Amount of lasagna Rico eats + Amount of lasagna His friend eats
Total lasagna ate by both Rico and his friend = 
Total lasagna ate by both Rico and his friend = 
Total lasagna ate by both Rico and his friend = 
Total lasagna ate by both Rico and his friend = 
The amount lasagna is left = 1 - Total lasagna ate by both Rico and his friend.
The amount lasagna is left = 
The amount lasagna is left =
The amount lasagna is left =
Answer:
a. 28˚
b. 76˚
c. 104˚
d. 56˚
Step-by-step explanation
a. because angle between tangent and chord is equal to the angle(s) in alternate segment.
b. because angles in triangles add up to 180˚, 180-28=152 and because isosceles triangle, 152/2=76˚
c. because angles in triangles add up to 180˚ and opposite angles in a cyclic quadrilateral add up to 180˚, 31+76=107, 180-107=73, 73-28=45, angles in triangle so 180-(31+45)=104˚
d. 28*2=56˚ because angles at circumference are half angles at centre
