I think yes but I'm not 100% sure to be honest
Answer:
1:2
Step-by-step explanation:
25:50 can be simplified down to 1:2. Think about ratios like fractions, since 25 can be divided into 50 two times, 25 is 1/2 of 50.
The height of the plant was 19.24 cm.
Turn the percent into a decimal: 0.74
Multiply the number by the decimal
26·0.74 = 19.24
Answer:
8.30%
Step-by-step explanation:
you look at .3, which is in the tenths place. then you look to the left, if the number is 5 or higher, you round the 3 up, but if the number's lower, you erase all the numbers to the left of the place you want to round at
Answer: 4x² + 4xy - 3y²
Concept:
When encountering questions that ask for simplifying algebraic expressions, using the FOIL method would be easier:
- <u>First</u>, which means multiplying the first terms together;
- <u>Outer</u>, which means that we multiply the outermost terms when the binomials are placed side by side;
- <u>Inner</u>, which means multiply the innermost terms together;
- <u>Last</u>, which means that we multiply the last term in each binomial together.
Solve:
<u>Given</u>
(2x - y) (2x + 3y)
<u>Expand parentheses and apply the FOIL method</u>
=4x² + 6xy - 2xy - 3y²
<u>Combine like terms</u>
=4x² + (6xy - 2xy) - 3y²
=
