Help plz what is 7-6v=-5-8v

1 answer:

3 0

v=-6 is the right answer. First you had to subtract by 7 from both sides of equation, and it gave us, $7-6v-7=-5-8v-7$ . And then simplify, and it gave us, $-6v=-8v-12$ . You can also add by 8v from both sides of equation, and it gave us, $-6v+8v=-8v-12+8v$ . Next simplify, and it gave us, $2v=-12$ . Then you divide by 2 from both sides of equation, and it gave us, $\frac{2v}{2}=\frac{-12}{2}$ . And finally simplify, and it gave us the answer is v=-6 is the right answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie

What is the length of the missing leg?

Crank

Answer:

$a=\sqrt{609}\\\\a\approx 24.67793$

Step-by-step explanation:

To solve for the leg of the missing right triangle, one must use the Pythagorean theorem. The Pythagorean theorem states the following,

$a^2+b^2=c^2$

Where (a) and (b) are the sides adjacent to or next to the right angle. (c) is the side opposite the right angle. Substitute in the given values and solve for the unknown,

$a^2+b^2=c^2\\$

Substitute,

$a^2+40^2=47^2\\$

Simplify,

$a^2+1600=2209\\$

Inverse operations,

$a^2=609$

$a=\sqrt{609}\\\\a\approx 24.67793$

Help i give 5 stars and a crown

REY [17]

Answer:

See below.

Step-by-step explanation:

1a)

Angles:

48, 90, 90, a.

Add:

48 + 90
= 138 + 90
= 228

Subtract:

360 - 228
= 132.

Angle a: 132.

1b)

To get angle h above 180°, We need to add h + 164:

h + 164
= 110 + 164
= 274.

h = 110.

This is how to get h over 180°.

The algebra tiles represent the perfect square trinomial x2 10x c. what is the value of c? c =

devlian [24]

The value of c for which the considered trinomial becomes perfect square trinomial is: 20 or -20

<h3>What are perfect squares trinomials?</h3>

They are those expressions which are found by squaring binomial expressions.

Since the given trinomials are with degree 2, thus, if they are perfect square, the binomial which was used to make them must be linear.

Let the binomial term was ax + b(a linear expression is always writable in this form where a and b are constants and m is a variable), then we will obtain:

$(ax + b)^2 = a^2x^2 + b^2 + 2abx$

Comparing this expression with the expression we're provided with:

$x^2 + 10x + c$

we see that:

$a^2 = 1 \implies a = \pm 1\\b^2 = 10\\b = \pm 10\\2ab = c\\\pm2(10)1 = c\\c = \pm 20\\$

Thus, the value of c for which the considered trinomial becomes perfect square trinomial is: 20 or -20
