Answer:
The side lengths are 10 by 7
Step-by-step explanation:
The area of a rectangle is
A = l*w
70 = (x - 11)(x - 8)
FOIL
70 = x^2 -8x-11x+88
Combine like terms
70 = x^2 -19x +88
Subtract 70 from each side
0 = x^2 -19x +88-70
0 = x^2 -19x+18
Factor
What number multiplies to 18 and adds to -19
-18*-1 =18
-18-1 = -19
0=(x-18)(x-1)
Using the zero product property
x-18=0 x-1=0
x=18 x=1
But x cannot x=1 because then the side lengths would be negative
x-18 = 10
x-11 = 7
The side lengths are 10 by 7
It would be asa they have 2 congruent sides, 2 angles, and they both share QS and by the reflexive prop QS=QS so it would be asa
Answer:
the answer for the question is 5/28
Answer:
a.
b.
Step-by-step explanation:
We are given that
Speed of red bike, v=24 km/h
Speed of blue bike, v'=12km/h
Distance of red bike when t=0
=10 km north
Distance of blue bike when t=0
=6km east
a. We have to find the expression of distance of red bike from Lawrence.
Let t be the time taken by red bike
Distance of red bike from Lawrence is given by
b.
Distance of the blue bike from Lawrence
Answer:
18/25 = 72%
Step-by-step explanation:
P(B ∪ F) = P(B) + P(F) - P(B ∩ F)
= 12/25 + 11/25 - 5/25
= 18/25
The probability a randomly chosen student plays either sport is 18/25 = 72%.
