So, we know the perimeter is 24 cm. and the top part is the left part, (x) + 2, but remember, we need to have it be a number that, multiplied by 2, is 24. So, using this formula, the length, (top / bottom) is 7, and x = 5. Because 5 + 5 = 10, and when length is +2, it adds up to 14. 10 + 14 = 24. So, length is 7, width, (left, right) is 5.
Answer:
well i think the answer is 80
Step-by-step explanation:
180=130 + 137+x
130-50+x
130-50=80
Answer:
1.
2.
3.
Step-by-step explanation:
Write in exponential form
Using the law of logarithm which says if
then
By comparison;
A = 16; b = 2 and x = 4
The expression becomes
Write in exponential form
Applying the same law as used in (1) above;
A = 2; b = 16 and
The expression becomes
Write in logarithm form
Using the law of logarithm which says if
then
By comparison;
b = 2; x = z and A = y
The expression becomes
A isn’t correct because there is 2 O’s on the left side and 3 on the right
B is incorrect because there is an S on the right but not on the left
C is incorrect because there are 2 Ca on the left side and 1 on the right
D is balanced as there are 2Na ok each side, 2Cl on each side,2H, and 1 SO4 on each side
