1. 4 -3y =1
2. 3 × 5 or 6
Step-by-step explanation:
I just guessed
Answer:
The answer is 36 tablespoons
Step-by-step explanation:
1/4 = 4 tablespoons
4*8 = 32
32 + 4 =36
We know, area of a parallelogram = b * h
Here b = 14
h = 6
So A = 14 * 6 = 84
In short Your Answer would be 84 Feet²
Hope this helps!
Answer:
18
Step-by-step explanation:
Remark
This is one of those questions that can throw you. The problem is that do you include the original rectangle or not. The way it is written it sounds like you shouldn't
However if you don't the question gives you 2 complex answers. (answers with the sqrt( - 1) in them.
Solution
Let the width = x
Let the length = x + 5
Area of the rectangle: L * w = x * (x + 5)
Area of the smaller squares (there are 2)
Area = 2*s^2
x = s
Area = 2 * x^2
Area of the larger squares = 2 * (x+5)^2
Total Area
x*(x + 5) + 2x^2 + 2(x + 5)^2 = 120 Expand
x^2 + 5x + 2x^2 + 2(x^2 + 10x + 25) = 120 Remove the brackets
x^2 + 5x + 2x^2 + 2x^2 + 20x + 50 = 120 collect the like terms on the left
5x^2 + 25x + 50 = 120 Subtract 120 from both sides.
5x^2 + 25x - 70 = 0 Divide through by 5
x^2 + 5x - 14 = 0 Factor
(x + 7)(x - 2) = 0 x + 7 has no meaning
x - 2 = 0
x = 2
Perimeter
P = 2*w + 2*L
w = 2
L = 2 + 5
L = 7
P = 2*2 + 2 * 7
P = 4 + 14
P = 18
A. Put these answers into your table :
5, 6.20, 7.40, 8.60, 9.80
B see pic
c yes there is a linear relationship between the letters and cost
D the equation is y=.60x+5
