40 + x
That's the expression you're looking for.
The expression that shows the temperature at the start of the day is 64 - 8 - 4
Answer:A≈46.38
Step-by-step explanation:
A=a2+2aa2
4+h2
AB=a2
Solving forA
A=AB(4h2+AB)+AB=6.4·(4·7.82+6.4)+6.4≈46.3808
Answer:
160 m²
Step-by-step explanation:
The surface area of the prism is the sum of the area of its surfaces. This prism has 5 surfaces, namely the front, back, right, left and bottom surface.
<u>Area of front surface</u>
Area of triangle= ½ ×base ×height
Base= 6 m
Height= 4 m
Area= 6(4)= 24 m²
<u>Area of back </u><u>surface</u>
Area of back surface
= area of front surface
= 24 m²
<u>Area of right </u><u>surface</u>
Area of rectangle= length ×breadth
Length= 7 m
Breadth= 5 m
Area= 7(5)= 35 m²
<u>Area of left </u><u>surface</u>
Area of left surface
= area of right surface
= 35 m²
<u>Area of bottom </u><u>surface</u> (base of prism)
Area of rectangle= length ×breadth
Length= 7 m
Breadth= 6 m
Area= 6(7)= 42 m²
The total surface area can be found by adding all of the surface areas we have found earlier.
Total surface area
= 24 +24 +35 +35 +42
= 160 m²
When two numbers are multiplied together that are exponents you multiply the bases amd add the exponents the relationship would simply be that the product <span>exponents are the sum of the exponents being multiplied in the question</span>
