Answer:
rectangular prism Area = 2L(W) + 2L(H) + 2W(H)
Step-by-step explanation:
Step 1 recognise the shape and unit ie) inches. cm etc.
Rectangular prism is like a cube but the length or height etc is disproportionate and therefore rectangular.and not cubic. even though its measured in cubic for volume and squared for surface area, it is added together each side square to allow for coverage.
Step 2
Count the sides you should automatically know how many sides for area
Full surface Area = how many sides
= 6
We then realise there is symmetry so we can multiply in pairs.
For spheres we multiply in 4;s Surface area = 4 π r2
Step 3
Know we have pairs how mnay pairs = 3
2L(w) + 2 L(h) + 2 W(h) = Surface area of rectangular prism
Show the multiplication and seperate with + sign
Step 4 Then add them all up and show unit square ^2 at end.
The equation of the line that passes through (2, -1) and is parallel to a line that has a slope of 3/4 is: 3x - 4y = 10.
<h3>What is the Equation of a Line in Standard Form?</h3>
The equation of a line can be expressed as, Ax + By = C, which is in standard form.
Given:
- A point (a, b) = (2, -1)
- Slope (m) = 3/4.
Plug the values into the point-slope form, y - b = m(x - a):
y - (-1) = 3/4(x - 2)
y + 1 = 3/4(x - 2)
4(y + 1) = 3(x - 2)
4y + 4 = 3x - 6
4 = 3x - 6 - 4y
4 + 6 = 3x - 4y
10 = 3x - 4y
3x - 4y = 10
The equation in standard form is: 3x - 4y = 10.

Answer:
12
Step-by-step explanation:
The length of the hypotenuse, PQ, can be found from the Pythagorean theorem:
PQ² = QR² +PR²
PQ² = 3² + 4² = 25
PQ = √25 = 5
The perimeter is the sum of side lengths:
P = 3 + 4 + 5 = 12
The perimeter of this triangle is 12 units.
2x²-2x-12=0
x²-x-6=0
(x-3)(x+2)=0
x-3 =0, x+2=0
x(1)=3, and x(2)=-2
The solutions make the equation true, and the solutions give x-intercepts of the graph of the equation.
(-2, 0) and (3,0) are x -intercepts for the graph of y = 2x²-2x-12
