4x I’d assume would be the answer
Answer:
A. 7x + 6y
Step-by-step explanation:
49x² + 84xy + 36y²
Factoring the perfect square:
(7x + 6y)²
7x + 6y is a factor.
Answer:
<u>36 in²</u>
Step-by-step explanation:
<u>Area of the figure</u>
- Area (small rectangle) left + Area (big rectangle) right
- 3 x (6 - 4) + 5 x 6
- 3 x 2 + 30
- 6 + 30
- <u>36 in²</u>
Side lengths: RS=7 and ST=7, and angle=90 degrees
Why?
Since second coordinates of R and S are the same so we can just count the length by adding first coordinate of R and first coordinate of S= |-3|+4=7
Since first coordinates of R is the same as first coordinate of T so we can just count the length by adding second coordinates of S and T=5+|-2|=7
Angle: RST is =90 degrees because triangle RST is right angled triangle. Why? Because RS is parallel to X axis(the same second coordinates of R and S) and ST is parallel to Y axis(the same coordinates of S and T) .
The exponent Marina should use for b is: D. 7.
<h3>How to Divide Exponents with the same Base?</h3>
When dividing, you subtract the exponents. I.e. .
Using the rule, we would also subtract the exponents of b in the simplified expression. Thus:
Subtract the exponents
4 -(-3) = 4 + 3 = 7.
Therefore, the Maria should use the exponent b = 7.
