Answer:
the 8 and 14 would be the coefficients
Step-by-step explanation:
coefficients are the numbers only next to the variables( like x or y) so since 8 and 14 are next to the variables they are the coefficients
12 because if u multiply 3*4 it is 12 and 4*3 is 12 so they both have 12 in common.
Answer:
1
Step-by-step explanation:
3. 8(3+8)
Explanation : 8x3 = 24 + 8x8 =64 which is congruent to 24 +64
Answer:
Second option: 81y^4 - 16x^2, the difference of squares
Step-by-step explanation:
(9y^2-4x)(9y^2+4x) is a special product named difference of squares, then we can apply this formula:
(a-b)(a+b)=a^2-b^2, with a=9y^2 and b=4x, then:
(9y^2-4x)(9y^2+4x)=(9y^2)^2 - (4x)^2
(9y^2-4x)(9y^2+4x)=(9)^2 (y^2)^2 - (4)^2 (x)^2
(9y^2-4x)(9y^2+4x)=81y^(2*2) - 16x^2
(9y^2-4x)(9y^2+4x)=81y^4 - 16x^2
