Answer:
<u>3</u><u>z</u><u>^2 + 3z - 6 </u>=0
3
3 (z^2 + z -2) = 0
3(z+2)(z - 1) = 0
z + 2-2 = 0 - 2
z = -2
z - 1 + 1 = 0 + 1
z = 1
Step-by-step explanation:
- factor out the GCF (3) and divide everything by it, and then set it equal to zero.
- since you have a degree of 2, factor it into two binomials that start with the square root of the first term and end with the square root of the second term.
- 3=0 is extraneous solution so we leave it, then we set each binomial equal to zero to solve for z.
note: your solutions is based on the degree or the exponent of the polynomial or the function.
Answer:
(a)Susan's measurements are incorrect. correct measurement is 2 cups of each sugar and flour.
(b)The triple measure is 3 cups of sugar and 3 cups of flour.
Step-by-step explanation:
The original measurements of the ingredients are:
Cups of sugar needed = 1 cup
and Cups of flour needed = 1 cup
Now, the double of the original measurements are:
Double of sugar = 2 x ( Previous measurement ) = 2 x ( 1 cup) = 2 cups
Double of flour = 2 x ( Previous measurement ) = 2 x ( 1 cup) = 2 cups
(a) Susan doubled the recipe with 2.1 cups of sugar and 33 cups of flour.
As the double measurements of sugar and flour are 2 cups each.
hence, Susan's measurements are incorrect.
b) The triple measurements of the ingredients are:
Triple of sugar = 3 x ( Previous measurement ) = 3 x ( 1 cup) = 3 cups
Triple of flour = 3 x ( Previous measurement ) = 3 x ( 1 cup) = 3 cups
hence the triple measure is 3 cups of each sugar and flour.
Answer: 234!!!
Step-by-step explanation: Cube or box's volume = length x width x height
Answer:
2340 mm
Step-by-step explanation:
We know that since the rectangular prism has a square base, the length and width are equal
So we have V = 10 * 10 * 15
For the small rectangular slab we can subtract 10 from 40 to get 30 for the length
Thus we have V = 30 * 4 * 7
Hope this helps
400 = 8b + y (subtract 8b from each side)
<u>-8b -8b </u>
400 - 8b = y
The answer is y = -8b + 400
i isolated y, which means i left it alone on one side of the equation
