Answer:
25.5
Step-by-step explanation:
first find the area od the rectangle than the triangle.
to find the area count the number of squares and use A=b*h
than do the same for the triangle using A=.5*b*h
15=3*5
10.5=.5*3*7
10.5+15=25.5
Answer:
4c + 4c + 16c + 90 = 360
Add the like terms
24c + 90 = 360
Subtract 90 when taking it to the other side of the equal
24c = 270
Divide 270 by 24 to get ur answer.
c = 11.25
Setup Average Equation:
_____________________
Average=Sum of our 4 numbers + unknown number of x
____________________________________
Total Numbers
15 = 3 + 19 + 8 + 32 + x
______________
5
Cross Multiply
___________
3 + 19 + 8 + 32 + = 15 x 5
x + 62 = 75
Subtract 62 from both sides of the equation to isolate x:
___________________________________________
x + 62 - 62 = 75 - 62
x = 13
13.54 +2.063 +0.14 +52.1= 67.843
so the answer is D.
Answer: 20x^8 y^10
Step-by-step explanation:
First off, simplify the exponential of x and y and the integers on the left side of the equation getting 32x^8 y^10 - 12x^8 y^10 = 20x^8 y^10
