Your photo is super blurry! I can’t read parts of the problems, so I can’t exactly help you. Sorry! Good luck.
Let’s write it simply, that helps us solve it easier.
6x^2+4x+8
Now, insert 7 in place of x.
6(7)^2+4(7)+8
Now, multiply.
42^2+28+8
Solve for exponents.
1,764+28+8
Add.
1,792+8
1,800
Hope this helps!
The answer is 3 of each. 3X7=21; 14X3=42, and 42+21= 63.
The answer is 23 because they have to add up to 90 :) - beanz
