If 35 cm represent the length of the plane which is 87.5 ft of the actual plane length. let 1 cm be x ft.
35 cm = 87.5 ft
1 cm = x ft
cross multiply this and the answer is 2.5 ft. Therefore, the scale drawing is 1 cm is 2.5 ft.
Answer:
3x^2-x-6
Step-by-step explanation:
f(x) = 3x^2 - 4
g(x) = x+2
(f - g)(x)= 3x^2 - 4-( x+2)
Distribute the minus sign
(f - g)(x)= 3x^2 - 4- x-2
Combine like terms
= 3x^2-x-6
This is a system of equations problem. Set up the 2 equations like so: If the angles are complementary then they add up to 90, therefore, a + b = 90. We also know that a is 16 more than b. The word "is" means equals and "more" is addition. Therefore, a is 16 more than b is "a = b + 16". Now sub in that value of a (b + 16) into the first equation and solve for b. Then back-substitute to solve for a. (b + 16) + b = 90 so 2b + 16 = 90 and 2b = 74. So b = 37. If b = 37, then a + 37 = 90 and a = 53. Check yourself to make sure that 37 + 53 add up to equal 90 (they do, just get used to checking yourself for accuracy).
I don’t know I just need points
6x[7+(15-8)]divided by 3=28 hope this helps
