Answer:
x=6,-4
Step-by-step explanation:
Ok so we know the 2 angles are congruent so you need to set them equal to each other. x^2+5x=7x+24. Then get the x's together so you subtract by 7x to get x^2-2x=24. You would then get 24 on the other side so subtract by 24 to get x^2-2x-24. You then would need to factor the equation out. The factored form would be (x-6)(x+4). Then set it equal to 0 to get 6 and -4.
Answer:
a(n)=6*2^(n-1)
Step-by-step explanation:
a(n)=a(1)r^(n-1)
a(1) = 6
a(2)=6r^1=12
r=2
a(n)=6*2^(n-1)
Answer:
22
Step-by-step explanation:
10*1=10
then as we know first we should do multiplier and division so,
2*60=120, 120/10=12
10+12=22
Answer:
B. 0.635
Step-by-step explanation:
Having a percent means its out of 100 so we can turn the percent into a fraction. 63.5/100
We cant have a decimal in our fraction, so we can multiply by 10 to get rid of it. (63.5*10)/(100*10)=635/1000
Since the denominator is a multiply of 10, we can convert the numerator into a decimal. .635
So your answer would be B. 0.635
