His brother spent 20. For Paul to $12 you need to times 4 by 3 to get 12. So you need times 5 by 4 which gives you the 20
Answer:
256 inches
Step-by-step explanation:
- area of a triangle is 1/2×base×height
- 1/2×32×16=256
Answer:
y = 62, x = 122
Step-by-step explanation:
Every triangle's sum of interior angles = 180°.
60 + 58 + y = 180
118 + y = 180
y = 62
Supplementary angles are adjacent angles that make up a straight angle (180 degrees)
58 + x = 180
x = 122
Answer: An inequality
Step-by-step explanation:
An inequality is a mathematical sentence written with a greater than
sign, or less than sign, or equal to sign or not equal to sign or more than two of these signs at the same time to join two expressions.
Answer:
Step-by-step explanation:
The given equation is ![\sqrt[3]{x+8}=-4](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%2B8%7D%3D-4)
.
We cube both sides of this equation to obtain;
![(\sqrt[3]{x+8})^3=(-4)^3](https://tex.z-dn.net/?f=%28%5Csqrt%5B3%5D%7Bx%2B8%7D%29%5E3%3D%28-4%29%5E3)
.
This implies that;
We group similar terms to obtain;
We simplify the right hand side of the equation to obtain;
Therefore x=-72 is the solution of the given equation.
