What are the answers I have to put in the yellow boxes?
valentinak56 [21]

The expression 1x² + 14x + 40 is a quadratic expression, and the answers in the yellow boxes are 40 and 14

<h3>How to complete the boxes?</h3>

The quadratic expression is given as:

1x² + 14x + 40

This implies that:

a = 1

b = 14

c = 40

Because a quadratic expression is represented as:

ax² + bx + c

The expressions in the yellow boxes are:

a * c and b

So, we have:

a * c = 1 * 40 = 40

b = 14

Hence, the answers in the yellow boxes are 40 and 14

koban [17]

Answer:

(7, 1/2)

Step-by-step explanation:

Multiply second equation by 2 and subtract.

3x - 4y = 19

- (4x - 4y = 26)

You get -x = -7

x = 7

Substitute x into any equation.

3(7) - 4y = 19

21 - 4y = 19

-4y = -2

y = 1/2

A right triangle has legs of 5 ft and 6 ft. What is the length of the hypotenuse? _____ ft.
yarga [219]

Answer:

2.) 7.8

Step-by-step explanation:

We can use Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

5^2 + 6^2 = c^2

25+36 = c^2

61 = c^2

Take the square root of each side

sqrt(61) = sqrt(c^2)

7.810249676 = c
