Answer:

<h2>4</h2>

Step-by-step explanation:

Put x = 3 and y = 2 to the expression 2x²- xy+y²- 4x​:

2(3)² - (3)(2) + 2² - 4(3)    <em>use PEMDAS</em>

=2(9) - 6 + 4 - 12

= 18 - 6 + 4 - 12

= (18 + 4) - (6 + 12)

= 22 - 18

= 4

Professor Lam is grading papers in the teachers' lounge. He has already finished grading 6 assignments, and is grading 4 more as
Delvig [45]

Answer:

Step-by-step explanation: If Professor Lam grades 4 papers per hour, in 11 hours he will graded 44 papers. (11 x 4= 44). He had previously graded 6 papers giving him a total of 50 papers graded. His assistant can grade 5 papers per hour, thus it would take him 10 hours to grade the same amount of papers as Professor Lam. (10 x 5= 50) Thus: 11 hours Professor Lam 50 papers graded; 10 hours his assistant 50 papers graded.

Please help me with this one!!
Tema [17]

Answer:

21 in^{2}

Step-by-step explanation:

The square in the middle has a length and width of 3, so multiply. <u>9</u>.

All of the triangles have a base of 3 and a height of 2. The area equation for triangles is

A=bh\frac{1}{2}

So base*height is 6. Divide that by 2 or multiply by 1/2.

You get 3. There are 4 triangles, so multiply <em>that</em> by 4. <u>12</u>.

Add 12 and 9 together, and you get:

21 in^{2}

I hope this helps!

Each square below represents one whole
likoan [24]

Answer:

52.

Step-by-step explanation:

shaded = (3²) + (2²)

shaded = 9 + 4

shaded = 13

Unshaded = (3 x 2) + (2 x 3)

Unshaded = 6 + 6

Unshaded = 12

All = 12 + 13

All = 25

100 / 25 = 4

4 x 13 = 26 x 2

26 x 2 = 52.
