PLEASE HELP WITH 4 AND 5!!!

Answer:

(x-5) (x-7)

Step-by-step explanation:

x²−12x+35

note that the constant term is 35 and the x-coefficient is -12

step 1: List factors of 35 : ±1, ±5, ±7,±35

step 2: observe the factors listed and ask ourselves the following questions:

1) What 2 factors in the list , when multiplied gives the constant 35

2) What same 2 factors when added gives the x-coefficient -12

by deduction or trial and error, we can see that -5 and -7, when multiplied gives 35 and when added gives -12. Hence these become the factors.

Hence the factors are

(x-5) (x-7)

The baker:

• Baked 90 muffins on Monday
• Baked 24 Blueberry muffins on Tuesday

On Monday. The baker baked 36 blueberry muffins and this is 40% of the total she makes. Assuming the total is x, the expression would be:

36 = x × 40%

36 = 0.4x

x = 36 / 0.4

= 90 muffins in total

On Tuesday, she makes 60 muffins of which blueberry muffins are 40%:

= 60 × 40%

= 24 blueberry muffins

In conclusion, the Baker baked 90 muffins in total on Monday and 24 blueberry muffins on Tuesday.

Answer:

Part A:  90; Part B:  24.

Step-by-step explanation:

The number of blueberry muffins is 40% of the total number of muffins.

Part A:  There are 36 blueberry muffins.  This is 40% of the unknown number of muffins, x; this gives us

36 = 0.4x

Divide both sides by 0.4:

36/0.4 = 0.4x/0.4

90 = x

There were 90 total muffins.

Part B:  40% of the total number of muffins, 60, gives us the unknown number of blueberry muffins:

0.4(60) = x

24 = x

There were 24 blueberry muffins.
