Answer:
4 times 5 = 20, and 20 is... well.. 20
Step-by-step explanation:
When a number has another number in parentheses by it, it means you multiply the numbers together. So 4(5) is the same as 4 times 5, which equals 20
Answer:
Answer: a
Step-by-step explanation:
Answer:
Width = 52 yards
Length = 208 yards
Step-by-step explanation:
(2 * 4x) + 2x = 10x
10x = 520
x = 52
52 * 4 = 208
(208 * 2) + (52 * 2) = 416 + 104 = 520 yards

<span>f(x) = x^2 - 12x + 7
First, separate the first two terms from the constant
f(x) = (x^2 - 12x) + 7
Next, half the coefficient of second term in the parenthesis (12x) and square the result. Make sure to subtract outside the parenthesis what you added inside so that the equation stays equal.
f(x) = (x^2 - 12x + 36) + 7 - 36
f(x) = </span><span>(x^2 - 12x + 36) - 29
Now, just factor the trinomial inside the parenthesis, lemme know in a comment if you don't know how to do this and I'll explain.
f(x) = (x(x - 6) -6(x - 6)) - 29
f(x) = (x - 6)^2 - 29
The polynomial is now in vertex form, and the value of a, as you can see, is 6.

It is 1.575×10∧10 as you can get the exponent number by counting the digit after the first number which is not 0 from the left.
