Answer:
- 4x² - 8x - 3
Step-by-step explanation:
We want to calculate
1 - (2x + 2)² ← expand using FOIL
= 1 - (4x² + 8x + 4) ← distribute parenthesis by - 1
= 1 - 4x² - 8x - 4 ← collect like terms
= - 4x² - 8x - 3
The answer is 33 cm^3
Square Volume: 3*3*3= 27 cm^3
Pyramid: 1/3 * 2 * 3^2 = 6 cm^3
27+6= 33 cm^3
Answer:
7x(5-4y)
Step-by-step explanation:
35x-28xy
7x(5-4y)
Given that y=kx
After substituting any of the given values, we will get constant k as -0.75 or -3/4
So the answer is B. -3/4
Based on the computer output of the scatter plot, the predicted foot length for a student with an arm span of 160 cm is: B. 22.15 cm.
<h3>What are Scatterplots?</h3>
- Scatter plot is a graphical tool that shows a trend between a dependent and independent variable.
- The trend line can be used to make predictions.
Given the scatter plot as shown above, at 160 cm arm length spam, if we trace it up to the trend line, the corresponding predicted foot length lies between 21 - 23 cm.
Therefore, based on the computer output of the scatter plot, the predicted foot length for a student with an arm span of 160 cm is: B. 22.15 cm.
