Answer:
4x² + 4x - 2
Step-by-step explanation:
The opposite is the negative value
The opposite of - 4x² - 4x + 2 is
- (- 4x² - 4x + 2) ← distribute parenthesis by - 1
= 4x² + 4x - 2
Answer:You could not use a table with a top that is 2 1/2 feet long and 1 1/2 feet wide
Step-by-step explanation:
The complete question is
Elena needs to find a table that will fit three cube-shaped cases, each containing a frog.If the volume of each case is 1,000 cubic inches, could she use a table with a top that measures 2 1/2 feet long and 1 1/2 feet wide?Explain
step 1
Find the length side of the cube-shaped case
we know that
The volume of the cube is equal to
where
b is the length side of the cube
we have
substitute
solve for b
step 2
Convert feet to inches
we have
step 3
Compare the dimensions of the table with the dimensions of the cube-shaped case
30 > 10
The length of the table is greater than the length side of the cube
18> 10
The width of the table is greater than the length side of the cube
therefore
You could not use a table with a top that is 2 1/2 feet long and 1 1/2 feet wide
Answer:
It's just a simultaneous equation
Step-by-step explanation:
Let a big bag of sugar = x
Let a small bag of flour = y
x+x+y = 12kg
2x+y = 12kg ... 1
x-y = 2kg ... 2
Add 1 and 2
2x+y = 12
+
<u> </u><u> </u><u>x</u><u> </u><u>-</u><u>y</u><u> </u><u>=</u><u> </u><u> </u><u>2</u>
3x = 14
x = 14/3 = <u>4.66</u>
Substitute value of x into 1
2(4.66)+y = 12
9.333 + y = 12
12 - 9.333= 12
y = <u>2</u><u>.</u><u>6</u><u>6</u>
