1. 5 and E, 6 and F, 7 and D, 8 and A, 9 and G
Answer:
A) 10^23
Step-by-step explanation:
if bases are the same and you're multiplying then:
keep the base and add the exponents
QRS = DRS + QRD
167 = x + 143 + x + 30
167 = 2x + 173
-2x = 173 - 167
-2x = 6
x = 6/-2
x = -3
DRS = x + 143
= (-3) + 143
= 140
B
To find the area you multiply width times height, here for the bigger rectangle, to find the area you multiply 7*6 and then add that with 6 * x because those are the width and height of the smaller rectangle.
Second part
I believe that Wiliam chose C because he accidentally thought that adding everything was correct. He added 7+6 to get 13 for the bigger rectangle and then for the smaller rectangle decided that to find the area you would add 6 and x.
