What multiplies to equal 50, but adds to equal 12?

Answers

Answer 1

Answer: 5 because 5x10=50 and 7+5=12

Answer 2

Answer: Nothing. If you are factoring you are going to need to use the quadratic formula for this problem.

2x2(6x – 1) – 3(6x – 1)
6x(2x2 – 3) – 1(2x2 – 3)
6x(2x2 + 3) + 1(2x2 + 3)

Answers

Hello,
Answer A

12x^3-2x²+18x-3
=2x²(6x-1)+3(6x-1)
=(6x-1)(2x²+3)

The factorization of the given expression by grouping yields(6x-1)(2x²+3).

What is factorization?

Factorization is a way in which the common factors of the terms in an algebraic expression are found. We have the expression 12x^3-2x²+18x-3 in which are to factorize by grouping.

In order to carry out this factorization by grouping we have to perform the following steps;

Identify common factors which are 2x^2 and 3
Apply the common factors to two groups of the portions of the expression as shown;

12x^3-2x²+18x-3

2x²(6x-1)+3(6x-1)

(6x-1)(2x²+3)

84 is 15% of what number

Answers

p% $= (p)/(100)$

$(15)/(100) = (15/5)/(100/5) = (3)/(20)$

$(3)/(20) *x=84$ ⇒ $3x=84*20$
$3x=1680$
So, x= $(1680)/(3) = 560$

$\boxed {x=560}$

x*15/100=84
x=84*100/15
x=8400/15
x=560
therefore the number is 560

Which statement is true?

Answers

Answer:

Two shapes have corresponding congruent parts if and only if the shapes are congruent and one shape can be mapped to the other using a series of rigid transformations. (The first option)

Step-by-step explanation:

The other three statements are false.

Two shapes can have corresponding congruent parts without being congruent. For example, a square and a rectangle can have congruent sides, but they are not congruent shapes.

Two shapes can be congruent without being able to be mapped to each other using a series of rigid transformations. For example, a sphere and a cube are congruent shapes, but they cannot be mapped to each other using only rigid transformations.

Two shapes can be non-congruent and be able to be mapped to each other using a series of rigid transformations. For example, a square and a rectangle can be mapped to each other using a combination of a rotation and a translation.
