2t + 3t = 6t is false. The correct answer is 5t.
y + y + y = y(1 + 1 + 1) is true. Correct answer is 3y.
3(2 + x) = 6 + 3x is true. This is an application of the distributive rule for mult.
2a + 2b = 4ab is false. a and b are separate variables with no given relationship to each other. Correct answer would be 2(a+b).
x + 3 = 4x is false. x + 3x = 4x would be true.
Answer: d
The two smallest sides have to add up to the largest one
Answer:
The area is 29 cm
Step-by-step explanation:
Since it's kinda hard to divided 11, I divided 6 by 2 to get 3. You get the area by multiplying. So there are three 3's, but one of them is redundant, so we multiple 3 x 3, which is 9. Then we multiply 11 by the other half, 3. 11 x 3 = 33. Then the same thing with the bottom. We half 6, 3, and them multiply it by the width. 3 x 3 = 9. Then we add them all up. 9 + 9 = 18 + 11 = 29 cm
2.25 is 2 1/4
so 1/4 between 2 and 3 on the number line
W = L - 5
A = W.L
14 = (L - 5).L
14 = L² - 5L
L² - 5L -14 =0
(L - 7)(L + 2) = 0 {factorized}
L = 7 / L = -2
In this case L would be equal to 7 because a length of anything can't be a negative number
Therefore, W = 2
Answer : Length = 7 Width = 2
