The given expression 5x(x−2)+6x−3(x²−7) will be equivalent to 2x²- 4x + 21. The correct option is D.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given expression is 5x(x−2)+6x−3(x²−7). The expression will be solved as below:-
E = 5x(x−2)+6x−3(x²−7)
E = 5x² - 10x + 6x - 3x² + 21
E = 2x² - 4x + 21
Therefore, the given expression 5x(x−2)+6x−3(x²−7) will be equivalent to 2x²- 4x + 21. The correct option is D.

(Level 4) In a bag of orange, red, and yellow, 60% are orange, and 10% are red. There
are 6 yellow marbles in the bag. If you increase the number of orange marbles by 50%,
how many orange marbles are in the bag?
Answers
The answer is 22 orange marbles. Let me explain. Since 60% are orange and 10% are red, the rest, 30% is yellow. So we learn that every 10% equals to 2 marbles. If you add 60% + 50% = 110%
90% = 18
And we have to add 4 more because 10%×2.
So the total comes to 18+4= 22.

The height of two boys are in the ratio of 4:5 the shorter boy is 80 cm what is the height of the taller boy?
Answers
Answer:
100cm
Step-by-step explanation:
The relationship between the ratio and the heights is 20. i.e 4 : 5 = 80 : 100
Hope this helps, please tag brainliest.
The height of the taller boy is 100cm.
What is ratio?Ratio, is a term that is used to compare two or more numbers. It is used to indicate how big or small a quantity is when compared to another. In a ratio, two quantities are compared using division.
Let the height of the taller boy be x cm and smaller boy be y cm.
According to the given question.
The ratio of height of the two boys is 4:5.
Since, it is obvious that 4:5 is the ratio of the height of smaller boy to the taller boy. Because k will be the ratio of proportionality then 4k will given the smaller value and 5k will give the larger value therefore, 4:5 represents the ratio of height of smaller boy to the taller boy.
[tex]\implies \frac{y}{x} =\frac{4}{5}[/tex]
Also, the height of the shorter boy is 80cm.
Therefore,
[tex]\frac{80}{x} = \frac{4}{5}[/tex]
[tex]\implies 80\times 5 = 4\times x[/tex]
[tex]\implies 400 = 4\times x[/tex]
[tex]\implies x = \frac{400}{4}[/tex]
[tex]\implies x = 100cm[/tex]
Hence, the height of the taller boy is 100cm.
