4.3
Step-by-step explanation:
2.15 times 2 is 4.3
Answer:
The standard for would be y = -3x^2 - 24x - 46
Step-by-step explanation:
To get this to standard form, start by squaring the parenthesis.
y - 2 = -3(x + 4)^2
y - 2 = -3(x^2 + 8x + 16)
Now distribute the -3
y - 2 = -3x^2 - 24x - 48
Now add the 2 to both sides
y = -3x^2 - 24x - 46
Answer:
A
Step-by-step explanation:
Formula for Volume: <em>L x W x H</em>
The length of the base, is 10 in.
width is 1.7 in.
height is 20 in.
Then, you simply multiply them all by together
10 x 20 = 200
(I did these first because it is more simple)
Then, 200 x 1.7 = 340
The exponent for volume must always be ^3 because there is 3 measurements required to find the volume. So the answer is A
Hope this helps!!

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.
Answer:x=-8
Step-by-step explanation:subtract 21 from both sides then simplify 31-21 to -8
