For the smaller triangle ;
15^2 + b^2 = 17^2
b = 8

To check the work
15^2 + 8^2 = 289
17^2 = 289

(This is if the bottom number on the smaller triangle says 15, its a bit hard to read..)

Tell whether the graph of the Quadratic function y=-3x squared +x+1 opens upward or downward

8_murik_8 [283]

Answer:

down

Step-by-step explanation:

y = -3x^2 +x +1

The coefficient of the x^2 term is negative so it opens facing down

X^2 coeffient

- means down

+ mean up

<h3>Answer: Choice D) $\sqrt{34}, 6, 2\pi, \sqrt{42}$ </h3>

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

Explanation:

Use a calculator to find the decimal form of each of the following below (values are approximate; rounded to 2 decimal places)

2pi = 6.28
sqrt(42) = 6.48
sqrt(34) = 5.83

We see that the order of the decimal values is: 5.83, 6, 6.28, 6.48

So the order of the terms, from smallest to largest, is $\sqrt{34}, 6, 2\pi, \sqrt{42}$

Will Mark Brainliest!!! Which statement represents the simplified form of the given equation and correctly describes the solutio

Iteru [2.4K]

The statement $14 \neq 15$ no solutions represents the simplified form of the given equation 6x + 14 = 3(2x + 5). Hence Option A is correct

<u>Solution:</u>

Given, equation is 6x + 14 = 3(2x + 5).

We have to find the correct options that represents the simplified form of the given equation and correctly describes the solution.

So, now let us simplify the given equation

⇒6x + 14 = 3(2x + 5) ⇒ 6x + 14 = 6x + 15 ⇒ 6x – 6x + 14 = 15 ⇒ 14 ≠ 15

As L.H.S not equals with R.H.S, no value of x can satisfy the equation and there will be no solution for given equation.

Hence, option A is correct.
