35 because you add 3 and 6 and that gives you 35x
Two multiply 2 monomials, you have to multiply the coefficients and add the degrees. For example
2x^2 × 3x^3 =
6x^5
F(8x+5)^-1=0.2
(8+5)^-1=0.077
5^-1=0.2
8x^-1=0.125
0.125-0.2=-0.075/0.2-0.125=0.075
Answer:
10.44 m
Step-by-step explanation:
Solve this as a triange. The base is 3m and the perpendicular is 10m. The angle between the base and wall is 90° so it will be a right angled triangle.
Solve this by Pythagoras theorm:
let length of ladder is c
base is b
And perpendicular is a
Acc to Pythagoras theorem:
C² = a² + b²
C² = 10² + 3²
C² = 100 + 9
C² = 109
√C² = √109
C = 10.44m
For me is D........
Im not shure
