don’t worry you’ll get the hang of it eventually! there are 3 key elements of a circle you have to remember: circumference=the perimeter diameter...Learn more

an isosceles triangle has always got two equal sides and two equal angles. there will always be one side that is shorter/longer than the others and ...Learn more

the capital is Washington D. C.

the first step is to expand the bracket and then make the new quadratic equation =0 by minusing 73 from both sides. 5(x^2 + 2x) =73 ...Learn more

it may be easier to visualise 300 as a product of prime factors using a prime factor tree. 300 / \ 2 ...Learn more

if angle abc=angle bca then we can assume the triangle is an isosceles. this means that side ab = side ac so 3x - 5 = 19 - x 3x + x = 19 + 5 ...Learn more

replace n with the numbers 1,2&3 3(1)-2=1 3(2)-2=4 3(3)-2=7 1,4,7 are the first 3 terms

abc=a x b x c = 2 x 3 x 5 = 30

6f + 5g - 3f + 3g 6f -3f +5g +3g 3f + 8g

k/4=7 k=4x7 k=28

5d=70 d=70/5 d=14

it is a triangular based pyramid

if your question is sqrt(144x56) then the answer is 24root14 if the question is sqrt(144)x56 then the answer is 12x56=672

either do lots of practice questions or you can message any of the tutors on here to help you out :)

to find the diameter of the sphere you have to find the diagonal of the cube by using the Pythagoras theorem twice. the first time is to find out ...Learn more

the easiest way to simplify an algebraic term like this is to take out the common fractions and common terms. in this case it is 1/3 and x. 2x/3 +...Learn more

group all the similar terms together and keep the x on one side of the equal sign and the numbers on the other side. 5 - x/2 - x - 1/3 = 1 (5-1/3)...Learn more

12 - 28c you have to multiply 4 by each golf the terms inside the brackets

any number in the 7 times tables are a multiple of 7. Or any number that can be easily divided by 7 is a multiple of 7.

interior angles are the angles found within a shape. For a regular polygon this can be worked out with a simple equation of: (no. of sides - 2) x ...Learn more

a rational surd is one that can be simplified into a rational number such as sqrt(4)=2 sqrt(16)=4 an irrational surd is one that can not be simpli...Learn more

generally, to find the area you have to do length x width. but in this case you’ve been given the area and the length so you have to inverse the equ...Learn more

(3^8 x 3^4)/(3^2 x 3^8) = 3^(8+4)/3^(2+8) = 3^12 / 3^10 = 3^2 = 9 when multiplying numbers with the same base number, you should add the powers. w...Learn more
