Answer:
The length of hypotenuse is 12.5
Step-by-step explanation:
First 7.5 x 7.5 = 56.25
Then 10 x 10 = 100
Add them together 56.25 + 100 = 156.25
Then square root 156.25 and you get 12.5
Answer:
3.3 recurring
Step-by-step explanation:
1) expand bracket
11-3a+6=27
2)rearrange equation
11+6=27+3a
11+6-27=3a
17-27=3a
-10=3a
-10/3=a
a=3.3 recurring
Answer:
5 • 10^-4 I evaluate this by using scientific notation.
To find the x intercept replace y with 0 in the equation and solve for x:
4x +3(0) = 12
Simplify:
4x +0 = 12
4x =12
Divide both sides by 4:
x = 12/4
x = 3
The x intercept would be (3,0)
