2(a-2)=3(a-5) Distrubutive Property

1 answer:

Brrunno [24]3 years ago

5 0

So in distributive property you multiply the outside number by the two inside so in this case 2(a) + 2(-2) = 3(a) + 3(-5)
Which will give you
2a+ - 4 = 3a + - 15
Or
2a-4=3a-15
Then if your solving for a your can subtract 3a from 2a giving you
- a-4=-15
Then add 4 to - 15
-a =-11
Then divide by negative 1 (this is so a isn't negative)
A=11
Hope this helps!

77. Find the greatest common factor (GCF) of the polynomial: 12x^4 + 8x^3 - 16x^2

Fed [463]

Answer:

4x^2

Step-by-step explanation:

The greatest common factor of 12, 8, and 16 can be no larger than the smallest difference between these numbers, which is 4. 4 is a factor of each number, so is the GCF of them.

The exponent of the greatest common factor of x^4, x^3, and x^2 can be no larger than the smallest of these exponents, which is 2. So, the GCF of the variable portion of the terms is x^2.

The product of the coefficient GCF and the variable GCF is ...

... 4x^2

jekas [21]

Answer:

13,3,9

Step-by-step explanation:

f(3)=4(-3)-1

= -12-1

=13

f(1)=4(1)-1

= 4-1

= 3

f(5)=4(5)-11

= 20-11

= 9

the area of a triangle is 6 and 3/8 square yards. The height of the triangle is 2 and 1/2 yards. What is the length of the base

Otrada [13]

Solution:

<u>Note that:</u>

Area of triangle = 6 3/8 yd²
Height of triangle = 2 1/2
Area of triangle = 1/2 x base x altitude

<u>Use the formula to find the base of the triangle.</u>

1/2 x base x altitude = 6 3/8 yd²
=> 1/2 x base x 2 1/2 = 6 3/8 yd²
=> 1/2 x base x 5/2 = 6 3/8 yd²
=> 5/4 x base = 6 3/8 yd²
=> base = 6 3/8 ÷ 5/4 yd
=> base = 51/8 x 4/5 yd
=> base = 51/2 x 1/5 yd
=> base = 51/10 yd

The length of the base is 51/10 yards.

Solving Rational equations. LCD method. Show work. Image attached.

Dmitry [639]

Answer:

$b=1$

Step-by-step explanation:

The given rational equation is

$\frac{2b-5}{b-2} -2=\frac{3}{b+2}$

The Least Common Denominator is $(b+2)(b-2)$ .

Multiply each term in the equation by the LCD.

$(b+2)(b-2)\times \frac{2b-5}{b-2} -(b+2)(b-2)\times2=(b+2)(b-2)\times\frac{3}{b+2}$

Simplify;

$(b+2)\times \frac{2b-5}{1} -2(b+2)(b-2)=(b-2)\times\frac{3}{1}$

$(b+2)(2b-5) -2(b+2)(b-2)=3(b-2)$

Expand and group similar terms

$2b^2-5b+4b-10 -2(b^2-4)=3b-6$

$2b^2-5b+4b-10 -2b^2+8=3b-6$

$-b-2=3b-6$

$3b+b=-2+6$

$4b=4$

$b=1$
