Answer:
all you need to do here is add and multiple
Long Piece: 5x
Short Piece: x
(x) + (5x) = 72
6x = 72
x = 12
Long Piece: 5x = 5(12) = 60
Answer: 12 cm and 60 cm
Answer:
3.13
Step-by-step explanation:
There were 5.23 apples and 2.1 of them were eaten by bob. How many are left?
F(x)=3x+2
(FG)(x)=3(x+5)+2
=3x+15+2
=3x+17
Answer: the equation is
4x^2 + 4x - 12
Step-by-step explanation:
A quadratic equation is an equation in which the highest power of the unknown is 2.
The general form of a quadratic equation is expressed as
ax^2 + bx + c
Where
a is the leading coefficient
c is a constant
Assuming we want to write the quadratic equation in x, from the information given, the roots which are given are -2 and 1 and the leading coefficient is 4.
Therefore, the linear factors of the quadratic equation will be (x+2) and (x-1)
the equation becomes
(x+2)(x-1)
= x^2 - x +2x - 3
= x^2 + x - 3
Given a leading coefficient of 4, we will multiply the quadratic expression by 4. It becomes
4(x^2 + x - 3)
= 4x^2 + 4x - 12
