-4/5 and -1/2
Taking the LCM of the 2 fractions we get the common denominator 10

-8/10 and - 5/10

Now we can see the second fraction (-5/10) is bigger
Thus the friend is wrong

You can break it down into a bunch of squares and rectangles. Find those areas and add them up.

The total area is :
7*10 + 5*5 + 4*12 = 143

In your own words, describe the process of multiplying binomials using the FOIL method. You can either write a paragraph describ

neonofarm [45]

Answer:

We can describe FOIL using the distributive property of multiplication. For real numbers x, y, and z the distributive property of multiplication states that

$(x + y)z = xz + yz$

Now let $z = v + w$ , where v and w are real numbers.

Then $(x + y)(v + w) = x(v + w) + y(v + w)$

Here, we can again use the distributive property of multiplication to get

$x(v + w) + y(v + w) = xv + xw + yv + yw$

Hence, it follows that

$(x + y)(v + w) = xv + xw + yv + yw$

This is the method of FOIL (first: xv, outside: xw, inside: yv, last: yw)

For example, $(1 + 2)(3 + 4) = 21 \\\text{and} \\1(3) + 1(4) + 2(3) + 2(4) = 3 + 4 + 6 + 8 = 21$

What is the solution of the following system of equations?<br> 2x + y = -7<br> -3x - 2y = 10

pentagon [3]

Answer:

the solution is (-4, -3)

Step-by-step explanation:

Multiply the first equation by 2. This produces 4x + 2y = -14.

Now combine this result with the second equation:

4x + 2y = -14

-3x - 2y = 10

------------------

x = -4

Subbing -4 for x in the first equation yields 2x - 4 = -7, or 2x = -3.

Then x = -3/2, and the solution is (-4, -3)
