Answer:
280 cm2
Step-by-step explanation:
1)find the area of square
A=LW
=10×10
=100
2) find the area of triangle
A=B×H÷2
=10×9/2
=45
Coz,there are 4 triangle we multiple by 4
=45×4
=180
3)find the total surface area by adding the two
=100+180
=280cm2
Answer:
C.4
Step-by-step explanation:
Since the values are of the same base....
we add the powers..because its multiplication...
;2^(-1/3 + 7/3)
;2^(6/3) = 2^2
;Ans = 2^2 = 4


Simplify:

Subtract 1.12 on both sides:


Multiply both sides by 2:


Answer:
x=1 and x =5
Step-by-step explanation:
We want to know when it crosses the x axis (f(x) =0) . From the graph, we can see the x value when y=0 is x=1 and x =5
