Answer:
C
Opening the bracket is the first order in solving arithmetic from BODMAS but to do that in this case we need to add 4^3 and 9 which first requires us to find 4^3
Answer:
Step-by-step explanation:
9th square number = 81
5th square number=25
81-25=56
56 is a multiple of 8 as 8 x 7=56
Answer:
a) x = 34
b) yes, it checks out
Step-by-step explanation:
2x - 5 = 3(4 + 1/2x)
multiply both sides by 2 to eliminate fraction
2[2x - 5 = 3(4 + 1/2x)] = 4x - 10 = 24 + 3x
x - 10 = 24
x = 34
<u>check</u>
2(34) - 5 = 3(4 + 34/2)
68 - 5 = 3(4 + 17)
63 = 3(21)
63 = 63
<h3>
Answer: 1.75 square feet</h3>
This converts to the improper fraction 7/4
======================================================
Work Shown:
3/4 = 0.75
area of triangle on the left = base*height/2 = 0.75*2/2 = 0.75 sq ft
area of triangle on the right = base*height/2 = 1*2/2 = 1 sq ft
total area = 0.75+1 = 1.75 sq ft
This converts to the improper fraction 7/4 because
1.75 = 1 + 0.75
1.75 = 1 + 3/4
1.75 = 4/4 + 3/4
1.75 = (4+3)/4
1.75 = 7/4
Answer:
Step-by-step explanation:
This is the concept of algebra, a function is defined as a relationship whereby each input has one and only one single output.
In our expression;
y=-3x^2-7x-6
this can be written as:
f(x)=-3x^2-7x-6
such that, given x=0,1,2,....
f(0)=-6,
f(1)=-16
f(2)=-32
This implies that y is a function of x.
