Answer:
the answer is 6
Step-by-step explanation:
what you will do is 3 x 4 and that equals 12 and since the triangle is a half you are going to divide by 2
It’s both a and b because every input has a unique output
y=-3x+-1 should work,
Edit i believe this is wrong i'll try to solve it correctly right not, sorry!
The answer is the 2nd choice
Answer:
Length: 430
Width: 100
Step-by-step explanation:
Length : x
Width: x - 330
Area = 43000
Area = length * width
43000 = x (x - 330)
43000 = x² - 330x
x² - 330x - 43000 = 0
x² - 430x + 100x - 43000 = 0 // Doing factorization
x (x - 430) + 100 (x - 430) = 0
(x+100)(x-430) = 0
x + 100 = 0
x = -100 (Since the length can not be negative)
x - 430 = 0
x = 430(This is the length)
Width: x - 330 = 430 - 330 = 100
Proof : 430 * 100 = 43000
