I would set this up as a a proportion:
·
17x = 1360
x = 20 cm
Answer:
10x + 12 and 6x² + 11x - 7
Step-by-step explanation:
The perimeter (P) of a rectangle is calculated as
P = 2l + 2w ( l is length and w is width )
= 2(2x - 1) + 2(3x + 7) ← distribute parenthesis
= 4x - 2 + 6x + 14 ← collect like terms
= 10x + 12
--------------------------------------------------
The area (A) of a rectangle is calculated as
A = lw
= (2x - 1)(3x + 7) ← expand using FOIL
= 6x² + 14x - 3x - 7 ← collect like terms
= 6x² + 11x - 7
Answer:
3.7x10^8
Step-by-step explanation:
did it on calc
Answer:
The answer is D. 2
Step-by-step explanation:
exponential form
exponents equal
move constant to the right
subtract the number
divide both sides by 2
C.
don’t actually put that
