Answer:

<em><u>7</u></em><em><u>2</u></em><em><u> </u></em><em><u>yd²</u></em>

Step-by-step explanation:

area of this figure = area of 1st rectangle + area of 2nd rectangle

= l×b + L×B

= 6 × 5 + 14 × 3

=30 + 42

= 72 yd²

Product of polynomials can be done by using distributive property of multiplication over addition. The needed product is: Option

<h3>What is distributive property of multiplication over addition?</h3>

Suppose a, b and c are three numbers. Then we have:

a(b + c) = a\times b + a\times c

(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)

<h3>What are like terms?</h3>

Those terms which have same variables raised with same powers.

For example, 5x^3 and x^3 are like terms since variable is same, and it is raised to same power 3.

For example x^3 and 4x^4 are not like terms as the variables are same but powers aren't same.

For the given case, the expression is 2x^4(3x^2 +4x +1)

Using the distributive property of multiplication over addition, we get the product result as:

2x^4(3x^2 +4x +1) = 6x^{4+2} + 8x^{4+1} + 2x^4 = 6x^6 + 8x^5 + 2x^4

(when like terms are multiplied, powers are added of the variables (same variable) due to property  a^b \times a^c = a^{b+c} )

What is an equation of the line that passes through the points (6,−4) and (−6,2)? Put your answer in fully reduced form
katovenus [111]
Y=mx+b
m=slope
b=yintercept
slope=(y1-y2)/(x1-x2)
(x,y)
x1=6
y1=-4
x2=-6
y2=2

(-4-2)/(6-(-6))=-6/12=-1/2
y=-1/2x+b
subsitute one point
(6,-4)
x=6
y=-4
-4=1/2(6)+b
-4=3+b
subtract 3
-7=b
y=-1/2x-7 is answer
