Add 77 -10 with its additive inverse.

Ganezh [65]

Answer: 77 - 10 = 67, and the additive inverse of 77 - 10 is 77 + 10. 77 + 10 = 87.

Hope this helps! This question was kind of confusing for me, because I didn’t understand why you said to add 77 - 10… is this is the incorrect answer sorry your question was worded weird

A square has a diagonal length of 5 cm. The area of the squareiscm2. Round answer to the nearest tenths ifneeded.

Whitepunk [10]

$\begin{gathered} \text{Diagonal}=5\operatorname{cm} \\ \text{Area}=\frac{D^2}{2} \\ \\ \text{Area}=\frac{(5cm)^2}{2} \\ \\ \text{Area}=\frac{25\operatorname{cm}^2}{2} \\ \\ \text{Area}=12.5\operatorname{cm}^2 \\ \text{The area of the square is 12.5 cm }^2 \end{gathered}$

If two points on a line are A(10, −3) and B(12, 9), the rise is __________, and the run is __________, so the slope of the line

kherson [118]

The rise is the difference in y-coordinates:

y₂ - y₁ = 9 - (-3) = 12

The run is the difference in x-coordinates:

x₂ - x₁ = 12 - 10 = 2

The slope is the quotient of rise over run:

m = 12/2 = 6

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

If two points on a line are A(10, −3) and B(12, 9), the rise is 12, and the run is 2, so the slope of the line is 6.

In triangle ABC, m?BAC = 50°. If m?ACB = 30°, then the triangle is triangle. If m?ABC = 40°, then the triangle is triangle. If t

kumpel [21]

use the pythagorean theorem: a^2 + b^2 = c^2

6^2 = 36

4^2 = 16

36-16 = 20.

the square root of 20 is either a.) the square root of 20 or b.) 4.4721... (rounded 4.5)
