Diagonals of a rectangle are congruent.
18x - 28 = x + 380
Solving for x, I get 17.
So, x = 17.
PR = 18x - 28
PR = 18(17) - 28
PR = 278
QS = x + 380
QS = 17 + 380
QS = 397
Answer:
Step-by-step explanation:
1. (3b)^5
= (3b)^2 * (3b)^3.
2. Width = area / length
= 10^4 / 10^3
= 10^(4-3)
= 10 m.
H^3+3h^2x+3hx^2+x^3 should be the answer
F(x)=x^2-3x+1/2, if f(4)
Substitute x with 4, to get
f(x)=x^2-3x+1/2
f(4)=4^2-3(4)+1/2
f(4)=16-12+1/2
f(4)=4+1/2
f(4)=4 1/2 or 4.5. Hope it help!
