Answer:
70 square millimeters
Step-by-step explanation:
Area of a trapezoid: A= h × (b¹ +b)/2
Add the top and bottom lengths, then divide by 2. This gives you the average width.
Here that is (4+10)/2 14/2 = 7
Multiply by the height, 10
7 × 10. = 70
Answer:
A product of a number and 12 is increased by 23
I hope this helps! Use slope intercept form to find your y intercept and slope. Once you plot your y intercept (0,1), use your slope (3) to go up three units and to the right one unit.
Answer:
$7
Step-by-step explanation:
To solve this one we will subtract how much he spends from what he has. At the start he had 19 and then spent 8 meaning he now has 8 less than when we started so 19-8 is 11. He now as 11 dollars, then he spend another 4 meaning we have to subtract another 4 dollars. 11-4 is 7. So he as 7 dollars left at the end.
I hope this helps and please don't hesitate to ask if there is anything still unclear!
