Answer:
20300m^2
Step-by-step explanation:
first try to imagine the shape bisected into a rectangle and a triangle
to find the missing part of the triangle or the bottom side you need to subtract 70m from 140 m
140m-70m=70m this will be the base of your triangle
now you need the side
230m-60m=170
triangle formula base x height/ 2
70m x 170m=a
11900m=a
now the rectangle
base x height=a
60m x140m=a
8400m=a
finally add the two quantities together
8400m+11900m=a
20300m^2=a
Answer:
96 square feet
Step-by-step explanation:
A = W x L
A = 8 x 12
= 96

Answer: x=−5 or x=5
Step-by-step explanation:
−3x4+27x2+1200=0
Step 1: Factor left side of equation.
−3(x2+16)(x+5)(x−5)=0
Step 2: Set factors equal to 0.
x2+16=0 or x+5=0 or x−5=0
x=−5 or x=5
Answer:
21(11 +3x) or simplified more, would be: 231 + 63x
Step-by-step explanation:
P E M D A S
First, Do what is in the parethesis
7 x 3(5 x 2 + 3x + 1)
7 x 3(10 + 1 + 3x)
7 x 3(11 +3x)
Since there are no exponents move on to the next step.
Then multiply.
21(11 + 3x)
I didn't know whether if you were trying to put 5x(2) or not, so it got me confused! Sorry if this isn't right equation! But I hoped this helped!
If simplifies even more, it would be
231 + 63x
(If they wanted it to be in simpilest form)
4) A
5)B
4.5% of 70 is 3.15 and times 3 is 9.45
