Answer:

a. 16

Step-by-step explanation:

Find the scale:

42 ÷ 28 = 1.5

Use this scale for QR to find MN:

24 ÷ 1.5 = 16

Binomial Coefficients (30pts) 1. Write (a + b)^2 as a polynomial in standard form. Show work (FOIL/distributive property).

Darina [25.2K]

Answer:

$a^2 + 2ab + b^2$

Step-by-step explanation:

Given

$(a + b)^2$

Required

Express as a standard polynomial

We have:

$(a + b)^2$

Rewrite as:

$(a + b)(a + b)$

Open bracket

$a^2 + ab + ab + b^2$

Add like terms

$a^2 + 2ab + b^2$

PLEASE PLEASEE ANSWER THE QUESTION IN THE PICTURE BELOW

KatRina [158]

Answer: Choice C

Vertex = (5, -2)

===============================================

Explanation:

Vertex form is $y = a(x-h)^2 + k$ where the vertex itself is located at (h,k)

As the name implies, we can very quickly pull out the coordinates of the vertex without doing much math at all.

In the case of choice C, we have $y= \frac{1}{2}(x-5)^2 - 2$ which is the same as $y = \frac{1}{2}(x-5)^2 + (-2)$ and we can see that h = 5 and k = -2. Therefore, the vertex is located at (h,k) = (5, -2)
