4 x 5 = 20
and
5 x 5 = 25
I'm sure a calculator could help you out with this, But if you don't have access to a calculator I'll show you how to multiply. It's just like adding, Let's use 6 x 7 for example. Take the first number ( Which is 6 in this case ) and look at the second number ( Which would be 7 ) The second number represents how many times you would add the first number together. So:
6 + 6 + 6 + 6 + 6 + 6 + 6 = 42 ( We add 6 together 7 times )
So
6 x 7 = 42
There are faster methods but this is probably the best way to start out.

Answer:
f(-3) = 18
Step-by-step explanation:
We need just substitute x with (-3) and calculate it.
f(-3) = (-3)² -2*(-3) + 3 = 9 + 6 +3 = 18
Answer:
This is an example of equation with two unknowns. Andre bought x pounds of zucchini and y pounds of broccoli and we also know that there was 10 pounds of veggies in total. So, we can write:
$1.5 • x + $2 • y = $17
x + y = 10
From the second equation we can say that:
y = 10 - x
We can now enter this value of y into the first equation:
1.5 • x + 2 • (10-x) = 17
1.5 • x + 20 - 2 • x = 17
1.5x - 2x = 17 - 20
-0.5x = -3
0.5x = 3
x = 6
If x=6, then y=10-6, which is 4.
That means that Andre bought 6 pounds of zucchini and 4 pounds of broccoli.
