Answer: B
Step-by-step explanation:
-9 - 6 - (-8) = -9 - 6 + 8 = -7
Answer:
x = -1
Step-by-step explanation:
-18=15-3(6x+5) Distributive Property
-18=15-18x-15 Combining like terms.
-18=18x Divide by the coefficient.
-1=x
what's the question though
Answer: Area is 1840units²
Step-by-step explanation:
From the given information,
Firstly, area of a rectangle is given as
A = l × b ie, length multiply by the breadth.
One of the side of the rectangle is known , AD = 16 , now to calculate the other side, we need some calculations.Since FE = 23 and
FD = DE ,,therefore,
DE = 23/2.
From the information, DE = 1/10 of DC. We now find DC the required side for finding the area of the rectangle by simple equation. Since DE = 23/2 , the equation now looks like this to get DC
23/2 = DC/10. Now , solving this
2DC = 23 × 10
2DC = 230
DC = 230/2
= 115.
Now the area of the rectangle will be
A = 16 × 115
= 1840units²
