Answer:
34
Step-by-step explanation:
13-(-21) = 13 + 21 = 34
The answer would be 84.6
You multiply 94 and 90 and then add a decimal point since you can’t go over 90.
That’s how I do it mentally.
Answer:
Area = 55 cm2
Step-by-step explanation:
It the base of the parallelogram was 9 centimeters and increased by 2, the new base has 9 + 2 = 11 centimeters.
It the height of the parallelogram was 4 centimeters and increased by 1, the new base has 4 + 1 = 5 centimeters.
Now, we can calculate the area of the parallelogram using the formula:
A = b * h
Where A is the area, b is the base and h is the height. So:
A = 11 * 5 = 55 cm2
154-2= 152/8= 19
answer is 19
