Factorise this expression as fully as possible 2x2 + 6x

Mathematics
1 answer:
butalik [34]2 years ago

Answer:

The factored expression is: 2x(x + 3)

Step-by-step explanation:

We are given the following expression:

2x^2 + 6x

To factorize it as fully as possible, we first find the GCF between the numeric values, and the coefficients:

Numeric:

GCF between 2 and 6 is 2, because:

2 - 6| 2

1 - 3|

1 and 3 are not divisible by the same number, so 2.

Coefficient:

Between x² and x, x.

Factorizing:

Simplifying by 2x.

2x(\frac{2x^2}{2x}+\frac{6x}{2x}) = 2x(x + 3)

The factored expression is: 2x(x + 3)

Can u plz solve it asap with explanation. Thank you. ​
Shtirlitz [24]

okay so you should know that the formula for a triangle is:

A=1/2×b×h

where b is breadth and h is height

A is area

so they already gave the area which is 16.2 and they already gave a side ( doesn't matter if it's b or h in this question)

so we put these into the equation of the area of a triangle

A=1/2×b×h

16.2=1/2 × 6 × h

then you will solve algebraically to get 5.4cm which is you answer

to check if correct you can always put in all numbers in equation and you should get 16.2cm

In this case it's correct ✌

If mBGC = 16x - 4 and mCGD = 2x + 13, find the value of x so that BGD is a right angle​
Lelu [443]

Hi there! :)

Answer:

\huge\boxed{x = 4.5}

m∠BGC = 16x - 4

m∠CGD = 2x + 13

m∠BGC + m∠CGD sums up to 90°, therefore:

(16x - 4) + (2x + 13) = 90

Combine like terms and simplify:

16x + 2x - 4 + 13 = 90

18x - 4 + 13 = 90

18x + 9 = 90

18x = 81

18x/18 = 81/8

x = 4.5
