Answer:

The answer is 66.

Step-by-step explanation:

Use order of operation.

Parenthesis goes first, so first you do the problem in parenthesis.

5-1+3=7

Next, combine the answer and the rest of the problem.

10+4*4/2*7.

I'm this problem, multiplication goes first, so to need to multiply 4 by 4.

4*4=16.

So now the problem should look like this:

10+16/2*7

Next, divide 16 by 2

16/2=8

That leaves you with 10+8*7.

Multiply 8 by 7.

8*7=56.

The last problem is 10+56.

10+56=66

Therefore, the answer is 66.

Determine whether the polynomial below can be factored into perfect squares. If so, factor the polynomial. Otherwise, select tha

Natasha2012 [34]

Answer:

C. $(4x-8)^2$

Step-by-step explanation:

We need to determine whether the given polynomial $16x^2-64x+64$ can be factored into perfect squares. If so, factor the polynomial. Otherwise, select that it cannot be factored into a perfect square.

$16x^2-64x+64$

$=16x^2-32x-32x+64$

$=16x(x-2)-32(x-2)$

$=(16x-32)(x-2)$

$=16(x-2)(x-2)$

$=16(x-2)^2$

$=4^2(x-2)^2$

$=(4(x-2))^2$

$=(4x-8)^2$

Hence final answe is choic C. $(4x-8)^2$

In an AP with 18 terms the common difference is $-3$−3 . If the nth term is $-5$−5, what is its first term?

erastova [34]

Answer:

Step-by-step explanation:

The n th term of an AP is

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here d = - 3 and $a_{18}$ = - 5 , thus

a₁ + (17 × - 3) = - 5

a₁ - 51 = - 5 ( add 51 to both sides )

a₁ = 46
