D.5
Step-by-step explanation:
A.a numerical or constant quantity placed before and multiplying the variable in an algebraic expression (e.g. 4 in 4x y).
B.a quantity or parameter that does not change its value whatever the value of the variables, under a given set of conditions.
C. More than one term that has a varibles or coeifficant the same.
D. Inbetween the addition signs are numbers how many indiviual numbers are there.
Answer: 8.4
Explanation: Because 1.2 7 times is 8.4
Step-by-step explanation:
The point-slope form of an equation of a line:
<em>m</em><em> - slope</em>
<em>(x₁, y₁)</em><em> - point on a line</em>
We have
Substitute:
Convert to the slope-intercept form
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
<em>use the distributive property</em>
<em>add 3 to both sides</em>
Convert to the standard form:
<em>multiply both sides by 2</em>
<em>subtract 5x from both sides</em>
<em>change the signs</em>
Answer:
82cm²
See explanation below
Step-by-step explanation:
The question is incomplete without the diagram of the rectangular prism and it's dimensions. We are to determine the surface area of the rectangular prism using it's net.
I would show you how to determine it using diagram below.
Find attached the diagram used in solving the question as well as the net obtained from the diagram.
Solution:
A net diagram is a 2-dimensional representation of a 3-dimensional solid in which case the solid is unfolded.
The net gives the total area of the sides and faces of the 3 dimensional figure.
The units of the diagram used are all in cm.
Using net diagram:
Area A = Area B = length × height = hl
Area C = Area D = width × length= wl
Area E = Area of F = height × width = hw
surface area of the rectangular prism = 2(wl + hl + hw)
w = width = 2cm
l= length = 7cm
h = height = 3cm
Insert the values in the formular
A = 2(2×7 + 3×7 + 2×3)
A = 2(14+21+6)
A = 2(41) = 82cm²
Surface area of the rectangular prism = 82cm²
