Part B What is the length, in feet, of the new sign?
Answer:
Part A) Using cross product x= 4.5*4/3
Part B ) x= 4.5*4/3= 18/3=6 Feet
Step-by-step explanation:
Length : Height
4.5 : 3
x : 4
Part A) Using cross product x= 4.5*4/3
Part B ) x= 4.5*4/3= 18/3=6 Feet
Answer:
I am not american, so I don't know if this is correct or now. You times 10*15 to get the surface area of one wall. Then you times that by 4 to get four walls. I think the answer is 600 ft
Step-by-step explanation:
hope it helps
distribution method
the answer would bex squared + 3x - 28
x^2-11x+28 (FOIL method)
I really need help on this

Answer:
y = x² + x - 4
Step-by-step explanation:
Given roots x = a and x = b, then the factors are
(x - a) and (x - b)
The function is then the product of the factors
y = a(x - a)(x - b) ← where a is a multiplier
Given roots are x = - 4 and x = 2 then the factors are
(x - (- 4)) and (x - 2), that is (x + 4) and (x - 2), thus
y = a(x + 4)(x - 2)
To find a substitute (6, 20) into the function
20 = a(6 + 4)(6 - 2) = a(10)(4) = 40a ( divide both sides by 40 ), thus
a = =
y = (x + 4)(x - 2) ← expand factors
= (x² + 2x - 8) ← distribute
y = x² + x - 4
