Answer:
<u>x = 20°</u>
Step-by-step explanation:
(4x-10)+x=90
4x-10+x=90
4x+x-10=90
5x-10=90
5x=100
x=20
Answer:
C
Step-by-step explanation:
you have to multiply 4 by x-7 thats equal to 4x - 28 then you have to substract 5 to 28 thats equal to 23 so the answer is 4x -23
Answer:
Tax: $3.20
Total: $43.20
Step-by-step explanation:
8% of $40 = 0.08 * $40 = $3.20
$40 + $3.20 = $43.20
Tax: $3.20
Total: $43.20
Step-by-step explanation:
We know that
- Area of the rectangle=Length×Breadth
➝(x+4)(x-9)=68
➝x(x-9)+4(x-9)=68
➝x^2-9x+4x+-32=68
➝x^2-5x-32=68
➝x^2-5x=68+32
➝x^2-5x=100
➝x^2-5x-100=0
- The equation has no real roots hence this situation can't be possible
I think it’s D because the definite can’t be a negative
