Use all 2,4,6,8 Once and any operation and brackets to find two equations that equal 24
Genrish500 [490]

Answer:

It is given that by using 2,4,6,8 once and any operation and brackets we have to make two equations which is equal to 24.

1. [8×6]÷(4-2)=48÷2=24 [ First multiplied 8 and 6 keeping them in a bigger bracket then divided by (4-2=2) by keeping it in a single smaller bracket.

2. [8×4]- (6+2)=32 -8=24 [Multiply 8 and 4 and then subtract (6+2=8) from it.This is equal to 24.

These are the two equations that i wrote for you , you can find many more by yourself.

Wewaii [24]

Answer:

area of square=l²

25sq.cm²=l²

l=5sq.cm

area of trapezium =(1/2)(a+b)h

a=5,b=(12+5)=17,h=5

area of trapezium=(1/2)(22)(5)

area=55cm²

Answer:

\huge\boxed{a=\dfrac{16}{3}=5\dfrac{1}{3}}

Step-by-step explanation:

\triangle ZYW\sim\triangle WYX\ (AAA)\\\\\text{Therefore corresponding sides are in proportion}\\\\\dfrac{YX}{YW}=\dfrac{YW}{ZY}\\\\\text{substitute}\\\\YX=a;\ YW=4;\ ZY=3\\\\\dfrac{a}{4}=\dfrac{4}{3}\qquad\text{multiply both sides by 4}\\\\4\cdot\dfrac{a}{4}=4\cdot\dfrac{4}{3}\qquad\text{cancel 4}\\\\a=\dfrac{16}{3}
