Answer:
2x2+17x+35
Step-by-step explanation:
=(2x+7)(x+5)
=(2x)(x)+(2x)(5)+(7)(x)+(7)(5)
=2x2+10x+7x+35
=2x2+17x+35
< is the correct symbol
3 x 2/4 = 1.5
1.5 is less than 3
so 1.5 < 3
Answer:
Step-by-step explanation:
y intercept
To find the y intercept, make x = 0
2(0) + y = - 6 zero times anything is 0
0 + y = -6
The y intercept is (0,-6)
x intercept
The x intercept happens when y = 0
2x + 0 = -6 zero added to anything = whatever you started with.
2x = - 6 Divide by 2
2x/2 = -6/2 Do the division
x = - 3
The x intercept = (-3,0)
He would make $117 because 7x15=105 and 1.50x8=$12.00 add that together you get 117
Answer:
Total cooking time = 20t + 15
The expression 15t + 20 is wrong.
Step-by-step explanation:
weight of chicken = t lbs
cook time per lb = 20 minutes
This means that:
1 lb weight requires a cooking time of 20 minutes
1 lb = 20 minutes
∴ t lbs = 20 × t = 20t minutes.
We were also told that each chicken required an extra cooking time of 15 minutes, in addition to the total cooking time due to the weight. Therefore, the total cooking time is calculated thus:
Total cooking time = cooking time due to weight + 15 minutes
Total cooking time = 20t + 15
Hence the expression 15t + 20 is wrong, due to the explanation given above.
