Answer:
- area = 14 square units
- perimeter = 19.1 units
Step-by-step explanation:
The base of the triangle extends from x=2 to x=6, a distance of 4 units.
The height of the triangle is 9 - 2 = 7 units.
Then the area is ...
A = (1/2)(4 units)(7 units) = 14 units^2
__
The length of the hypotenuse is given by the Pythagorean theorem.
h^2 = 4^2 +7^2 = 16 +49 = 65
h = √65 ≈ 8.1
The perimeter is the sum of the side lengths:
P = 4 + 7 + 8.1 = 19.1 . . . units

4s=amount of grams of protine in straberry for s ounces
3b=amount of grams of protine in banana for b ouces
total ounces is 6
s+b=6
total grams is 22
4s+3b=22
s+b=6
4s+3b=22
those are the 2 equations
a.
s+b=6
4s+3b=22
b. elmination, we can elminate alll the b's and have 1s left
c.
multiply first equaiton by -3 and add to second
4s+3b=22
<u>-3s-3b=-18 +</u>
1s+0b=4
s=4
sub
s+b=6
4+b=6
minus 4
b=2
4 oz straberry
2 oz banana
3^2 + 4^2 = 5^2
65/5=13
3x13 =39
4 x 13= 42
Answer:
<h2>S.A. = 234 mm²</h2>
Step-by-step explanation:
The formula of a surface area of a rectangular prism:
l - length
w - width
h - height
We have l = 15 mm, w = 3 mm, h = 4 mm. Substitute:
