Answer:
7
Step-by-step explanation:
Substitute in numbers : 2(5)+3(6) /4
Combine Like Terms : 10+18/4 = 28/4
Answer : 7
To find your answer you must substitute y for 0.8
4x + (8)(0.8) = 40
Now solve for x
====================================================================
SOLVING...
<span>4x + (8)(0.8) = 40
</span><span>4x + 6.4 </span>= <span>40
</span>
Subtract 6.4 from each side
<span><span><span>4x</span>+ 6.4 </span>− 6.4 </span>= <span>40 − <span>6.4
</span></span>4x = 33.6
Divide each side by 4
4x ÷ 4 = 33.6 ÷ 4
x = 8.4
Answer:
B
Step-by-step explanation:
The rest of the options are possible using an atm card. but using it to deposit is not possible.
Since it is x^3 cubed it has 3 maximum roots
by the zero multiplication property of function
if you plug find a root then you can deduce it is a factor in other words if f(x)=(x-a)(x-b)
then f(a)=0 and f(b)=0
so
f(2)=8+8-32-32= -48 therefore it is not a factor
f(-2)=-8+8+32-32=0 hence it is a factor
f(4)=64+32-64-32=0 it is a factor
f(-4)=-64+32+64-32=0 it is a factor
f(-6) it is not a factor via the fundmental therom of algebra
f(x)=(x+2)(x-4)(x+4)
=(x^2-16)(x+2)=x^3+2x^2-16x-32 which checks our work
Answer:
d) 24.2 cm²
<em>Area of equilateral triangle A = 24.22 cm²</em>
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
<em> Perimeter of equilateral triangle = 3 a</em>
Given Perimeter of equilateral triangle = 22.45 cm
now 3 a = 22.45
Dividing '3' on both sides,we get
a = 7.48 cm
<u><em>Step(ii):</em></u>-
<em>Area of equilateral triangle</em>
<em> </em>
<em></em>
<em> </em>
<em></em>
<em> A = 24.22 cm²</em>
<u><em>Conclusion</em></u><em>:-</em>
<em>Area of equilateral triangle A = 24.22 cm²</em>
