the number=A

5xA/7+A=2

5A/7 +A =2

5A/7=2-A/1

7(2-A)=1(5A)

14-7A=5A

14=5A+7A

14/12=12A/12

A=14/12

A=7/6

Factor completely 4x2 − 8x − 60. (4x − 20)(x + 3) 4(x − 5)(x + 3) (4x − 4)(x + 15) 4(x − 1)(x + 15)
katovenus [111]

after complete factorization of 4x^2-8x-60 the answer is 4(x+3)(x-5)

Step-by-step explanation:

We need to factor 4x^2-8x-60

Taking 4 common and factorizing:

=4(x^2-2x-15)\\=4(x^2+3x-5x-15)\\=4(x(x+3)-5(x+3))\\=4(x+3)(x-5)

So, after complete factorization of 4x^2-8x-60 the answer is 4(x+3)(x-5)

If f(x) = 3x² tlo, what is f(-7)?
tia_tia [17]

Answer:

Step-by-step explanation:

Be careful how you handle this.

f(-7) = 3(-7)^2

f(-7) = 3* 49     Notice the minus sign disappears. That's because there are 2 of them.

f(-7) = 147
