Answer:
a^3b^4
Step-by-step explanation:
You have 3 a's, so that would be

and you have 4 b's so that would be

so putting it together gives you

formula= LCM ×GCD of the numbers ÷ The first number
90 × 7 = 630 , it's not hard, it's easy
Answer: The correct congruence statement is
.
Explanation:
It is given that A triangle Q D J. The base D J is horizontal and side Q D is vertical. Another triangle M C W is made. The base C W and side M C are neither horizontal nor vertical. Triangle M C W is to the right of triangle Q D J.
The sides Q D and M C are labeled with a single tick mark. The sides D J and C W are labeled with a double tick mark. The sides Q J and M W are labeled with a triple tick mark.
Draw two triangles according to the given information.
From the figure it is noticed that



So by SSS rule of congruence we can say that
.
The answer to number one is C
and the answer to number two is A
