Question 1

Answer:

Step-by-step explanation:

This problem can be done without the Distance Formula (which is a way to find the distance between any two points in the plane).

The attached image shows the points and segments joining them.

PQ = 5 because the points are on the same horizontal line, and you can count spaces between them (or subtract x-coordinates: 4 - (-1) = 5).

PR = 12 because the points are on the same vertical line; count spaces or subtract y-coordinates, 7 - (-5) = 12.

The triangle is a right triangle, so the Pythagorean Theorem can be used to find the length of the hypotenuse.

$(\text{leg})^2+(\text{leg})^2=(\text{hypotenuse})^2$

$(QR)^2=5^2+12^2=25+144=169\\QR=\sqrt{169}=13$

The perimeter of the triangle is 5 + 12 + 13 = 30

Please solve asap pls x

Answer:

$x=\frac{26}{5}$

Step-by-step explanation:

$\frac{10x+4}{7}=8$

Multiply both sides by 7:

$\longmapsto$ $\frac{7\left(10x+4\right)}{7}=8\times \:7$

$\longmapsto$ $10x+4=56$

Subtract 4 from both sides:

$\longmapsto$ $10x+4-4=56-4$

$\longmapsto$ $10x=52$

Divide both sides by 10:

$\longmapsto$ $\frac{10x}{10}=\frac{52}{10}$

$\longmapsto$ $x=\frac{26}{5}$
