Evaluate each expression for the given value. 1. 5x – 11, for x = 6
2. 3a² + 7 - 2a, for a = 4
3. – 2n + 8, for n= -6
4.3(2y - 1) - 4y + 6, for y = 4

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140

step-by-step explanation:

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45
