Start by adding 7, then add 7x2, then 7x4, then 7x8, etc. 2 + (7x1) = 9 9 + (7x2) = 23 23 + (7x4) = 51 51 + (7x8) = 107 The next number is 219.
"What is 1 + 1?" is an easy math question in any grade.
by cross multiplying is a easy method to use just multiply numerator from a fraction and denominator from another fraction to get the answer on the left side then you switch sides by denominator multiplying numerator to get the answer on the right side of the fraction from the for example 7/8 and 3/4 7x4=28 for 7/8 and 8x3=24 on 3/4 to prove it 7/8 is larger than 3/4
Start out looking at them. 7x1=7 odd 7x2=14 even 7x3=21 odd 7x4=28 even 7x5=35 odd 7x6=42 even... so it looks like half might be even and half odd, This is because if we look at the numbers 1-14, ie 1,2,3,4,5,6,7,8,9,10,11,12,13. and 14, they alternate odd and even and since 7 is odd and odd times an even is always an even number and an odd times an odd is always an odd number. So to answer the question we need only look at the number of odd numbers between 1 and 14 inclusive. There are 6 so 1,3,5,7,9,11,13 give odd multiples ANSWER: so 7 odd multiples of 7 between 1 and 100
Polynomials can be classified based on the number of terms they contain. A polynomial with one term is called a monomial, such as 5x or -2y^2. A polynomial with two terms is called a binomial, like 3x + 2 or 4y - 7. A polynomial with three terms is called a trinomial, for example, 2x^2 + 5x - 3. Polynomials with more than three terms are simply referred to as polynomials.
7x4 equals 28.
An expression. It can be factored out slightly too: 2x6 + 5x3 - 7x4 = x3(2x3 - 7x + 5)
7x4=28
31
50
The answer is: 49
7 x 4 = 28
7x6=42 7x4=28
7x4=28 days
the answer is 28(7x4=28)
7x2*x2 = 7x4
Commutative i think dont blame me if wrong
